English: Reading Comprehension

Q. Read the given passage carefully:

My next pet was a pigeon, the most revolting bird to look at, with his feathers pushing through the wrinkled scarlet skin, mixed with the horrible yellow down that covers baby pigeons and makes them look as though they have been peroxiding their hair.
Because of his repulsive and obese appearance, we called him Quasimodo. Since he had an unorthodox upbringing, without parents to teach him, Quasimodo became convinced that he was not a bird at all, and refused to fly. He walked everywhere. He was always eager to join us in anything we did. He would even try to come for walks with us. So you had to either carry him on your shoulder, which was risking an accident to your clothes, or else you let him walk behind. If you let him walk, then you had to slow down your own pace to suit his, for should you get too far ahead you would hear the most frantic and imploring coos and turn around to find Quasimodo running desperately after you.

Q. Read the questions given below and answer the correct option.

Q1. The narrator describes the pigeon as a ‘revolting bird’ because
a) he could not fly
b) he had to be carried everywhere
c) he had wrinkled skin covered with yellow feathers
d) he was fat

Q2. Quasimodo got his name because
a) he was a fat and ugly
b) he was attractive
c) he could not fly
d) he love behaving like human beings

Q3. We know that Quasimodo was always eager to go on walks because
a) he walked everywhere
b) he did not know how to fly
c) he complained loudly if he was not taken along
d) he always copied whatever humans did

Q4. Quasimodo protested when he was
a) left at home
b) lifted on human shoulders
c) taken for a walk
d) left behind during walks

Q5. The phrase ‘risking an accident to your clothes’ means
a) the bird pecked at their clothes
b) there was a chance of the bird soiling their clothes
c) the bird risked a fall
d) the bird did not like their clothes


Q. Read the passage given below carefully
The idea of euthanasia, of hastening the death of someone from motives of compassion, covers two main situations. The first is where someone is close to death and can be kept alive briefly, with intensive medical care. The official reason for the use of every possible technique on patients, for whom there seems no hope, is that we never know that there is no hope of at least a brief recovery.
The second situation, in which it is proposed to end the life of someone who is not expected to die at once from natural causes, is more morally doubtful. In so far as the suggestion may be based on the notion of the ‘quality of life’ experienced by the patient, this is an inadequate approach to human beings. At one extreme we may be dealing with a birth that cannot be called ‘human’ at all: such a being likely to live at the most for only a few hours. Many feel that during this time it ought to be given ordinary  nursing care. Bringing to an end of the life of say, a spastic child, by the deliberate refusal of the fullest medical care seems morally indefensible.

Q. Read the questions given below and answer the correct option.

Q6. Euthanasia means
a) a place in Asia
b) bringing about gentle and easy death
c) enthusiasm
d) the youth in Asia

Q7. One reason for trying all possible measures to save a person is
a) death is horrifying
b) there is possibility of recovery
c) doctors need to be compassionate
d) science may invent more sophisticated machines later

Q8. The people who argue for euthanasia advocate it saying
a) the patient is not living a qualitative life
b) we must not spend quality resources on a sick person
c) we should not bother about the ailing
d) it can be defended morally

Q9. The words ‘………………dealing with a birth that cannot be called ‘human’ at all’ implies
a) humans have no control over birth and death
b) the person may survive only for a very brief period
c) doctors are incapable of saving people
d) the patient may want to die

Q10. The writer finds it unpardonable to
a) end the life of someone who is not expected to die at once from natural causes.
b) end the life of a spastic child
c) end the life of an infant who is likely to live only for a few hours
d) end the life of a human being

D. Rs. 275 crores

10. In how many of the given years were the exports more than the imports?
A. 1 
B. 2
C. 3 
D. 4

Answers:
1. Answer: (B)
20% of the total funds to be arranged = Rs. (20% of 57600) crores
= Rs. 11520 crores = Rs. 11486 crores. (Approx)
Rs. 11486 crores is the amount of funds to be arranged through External Assistance

2. Answer: (C)
Shortage of funds arranged through External Assistance = Rs. (11486 - 9695) crores
= Rs. 1791 crores.
Increase required in Market Borrowing = Rs. 1791 crores.
Percentage increase required = {[(1791 / 29952) ] x 100}% = 5.98%  = 6%. (Approx)

3. Answer: (C)
Amount permitted = (Funds required from Toll for projects of Phase II) + (10% of these funds)
= Rs. 4910 crores + Rs. (10% of 4910) crores
= Rs. (4910 + 491) crores
= Rs. 5401 crores.

4. Answer: (C)
Central angle corresponding to Market Borrowing =[(29952/57600)] x 360º = 187.2º

5. Answer: (B)
Required ratio = 4910/29952= 1/6.1 = 1/6 (Approx)

6. Answer: (D)
The ratio of imports to exports for the years 1998 and 1999 are 1.25 and 1.40 respectively.
Let the exports in the year 1998 = Rs. x crores.
Then, the exports in the year 1999 = Rs. (500 - x) crores.
1.25 = 250/x
x = 250 /1.25 = 200 ( Using ratio for 1998
Thus, the exports in the year 1999 = Rs. (500 - 200) crores = Rs. 300 crores.
Let the imports in the year 1999 = Rs. y crores.
Then, 1.40 = y / 300
y = ( 300 * 1.40 ) = 420
Imports in the year 1999 = Rs. 420 crores.

7. Answer: (C)
The imports are minimum proportionate to the exports implies that the ratio of the value of imports to exports has the minimum value.
Now, this ratio has a minimum value 0.35 in 1997, i.e., the imports are minimum proportionate to the exports in 1997.

8. Answer: (D)
The graph gives only the ratio of imports to exports for different years. To find the percentage increase in imports from 1997 to 1998, we require more details such as the value of imports or exports during these years.
Hence, the data is inadequate to answer this question.

9. Answer: (B)
Ratio of imports to exports in the year 1996 = 0.85.
Let the exports in 1996 = Rs. x crores.
Then, 272/x = 0.85
x = 272 / 0.85= 320
Exports in 1996 = Rs. 320 crores.

10. Answer: (D)
The exports are more than the imports imply that the ratio of value of imports to exports is less than 1.
Now, this ratio is less than 1 in years 1995, 1996, 1997 and 2000.

Thus, there are four such years.

Details of Triangle and its Properties - Part - II

As we all know, a triangle is a shape that consists of three sides and three angles. Taking a look at the triangle's angles often helps us find out what kind of triangle we are dealing with.

Here are some facts to remember:

  • The three angles in a triangle always add up to 1800
  • The three angles of an equilateral triangle are all equal to 600
  • Two angles of an isosceles triangle are equal.
  • One angle of a right-angled triangle is 900
  • All angles of an acute-angled triangle are acute angles, thus smaller than 900
  • One angle of an obtuse-angled triangle is obtuse, thus larger than 900 and smaller than 1800


If two triangles are congruent they have equal sides, equal areas. 

Condition for congruence:



1. SAS condition



If two sides and the included angle of one triangle is equal to the corresponding sides and included angle of the other triangle, then both triangles are congruent.
AB = DE, BC = EF and ∠B = ∠E, then ΔABC≈ΔDEF

2. ASA condition


If two angles and the included side of one triangle is equal to the corresponding two angles and    the included side of the other triangle, then both triangles are congruent.

If ∠A = ∠D, ∠B = ∠E and AB = DE, then ΔABC≈ΔDEF

3. SSS condition


If three sides of one triangle is equal to the corresponding three sides of other triangle then both    triangles are congruent.

  If AB = DE, AC = DF and BC = EF, then ΔABC≈ΔDEF



4. RHS condition


If the two triangles are right-
angled triangle and hypotenuse and one side of one triangle is equal    to the hypotenuse and corresponding side of other triangle, then both triangles are congruent.

if ∠B =∠E = 90°, AC = DF and AB = DE or BC = EF, then ΔABC≈ΔDEF

Note:  

 i.   All the congruent triangles are similar but all similar triangles are not congruent.

 ii.  The ratio of the areas of two similar triangles is equal to the ratio of the squares of any two corresponding sides.

The following four theorems are most important in solving questions on triangles.

Pythagoras’ theorem: In a right angle triangle the square of the hypotenuse is equal to the sum of the squares of other two sides.
Pythagorean triplet: There are certain triplets which satisfy the pythagoras’ theorem and are commonly, called pythagorean triplet.

 For example: 3, 4, 5;    5, 12, 13;    24, 10, 26;    24, 7, 25;    15, 8, 17

Appolonious theorem: 


In triangle ABC, AD is median, which divides BC into two equal parts. Then,
AB2+AC2=2(AD2+BD2)=2(AD2+DC2)



 Stewart theorem:


In Triangle ABC, AD divides side BC in the ratio m and n. (Here AD need not be median) then, 

m.b2+n.c2=a(d2+mn)











Mean proportionality and Mid Point theorem:




In the first triangle, DE // BC so AD/DB=AE/EC




In the second triangle, D and E are mid points of AB and AC respectively. Which implies, AD/DB=AE/EC=1

Also, DE=1/2BC

(b) 40%
(c) 60%                                        
(d) 45%


Answer with Explanation:
1.       (d) 

2.       (c) Let the CP = Rs. 100
Then, SP = Rs. 120
Let the marked price = Rs. x
Then, 90% of x = Rs. 120
= x = [(120 x 100)]/90 = 133  1/3
Hence, the marked price is 33  1/3 % above the cost price. 

3.       (a) Total CP = Rs. 100
Total SP =
= Rs. (60 + 20 +25)
= Rs. 105
\ Gain = 5%

4.       (d) Total actual C.P.
= Rs. (500 x 10 + 2000)
= Rs. 7000
Total S.p.
= Rs. (5 x 750 + 5 x 550)
= Rs. 6500
Loss = 7000-6500=  Rs. 500
Loss percent =( 500/700) x 100 = 50/7 = 7 1/7 %

5.        (b) Let C.P of each orange be Re. 1
Then C.P. of 10 oranges = Rs. 10
S.P. of 10 oranges = Rs. 12
Gain % = 20% 

6.       (a) Let the CP of 1 orange = Re. 1
\ CP of 10 oranges = Rs. 13
\ Gain percent = ( 13 – 10)/10  = 100
= 30%

7.       (b) Total Profit = 15 – 12 = Rs. 3
% gain =( 3/12) x 100 = 25% 

8.       (a) Let the man buy 24 (LCM of 8 and 12) oranges.
\ C.P. of 24 oranges =  (34/8) x 24
= Rs. 102
S.P. of 24 oranges
=( 27/12) x 24  = Rs. 114
Gain = 114 – 102 = Rs. 12
 Rs. 12 º 24 oranges
\ Rs. 45 º ( 24/12) x 45
90 oranges 

9.       (d) Let the printed price of the book be Rs. x.
\ Selling price = 90% of x = Rs. 9x/10
If the CP of the book be Rs. y. then,
Y + 112/100 = 9x/10
y/x = 9/10) x 100/112 = 45/56

10.   (a)
