Directions: Each question below contains a statement followed by Quantity I and Quantity II. You have to study the information along with the question and compare the value derived from Quantity I and Quantity II, then anwer:

1
Quantity I: Speed of boat in still water, if a man can travel 54 km downstream in 9 hours and 40 km upstream in 10 hours.

Quantity II: Speed of boat in still water, if a man can travel 45 km downstream in 9 hours and the speed of stream is 1 kmph.
 
» Explain it
C
Quantity I:
Let speed of boat = x kmph, speed of stream = y kmph

upstream speed = x – y, downstram speed = x + y
x + y =  54
9

x + y = 6 ....1
 
x – y =  40
10

x – y = 4 ....2

equation 1 + equation 2

x = 5

speed of boat = 5 kmph

Quantity II:

Let speed of boat = x kmph, speed of stream = 1 kmph

downstream speed = x + 1

45  = x + 1
9

5 – 1 = x

x = 4

Speed of boat = 4 kmph

Quantity I > Quantity II

Hence, option C is correct.

2
Quantity I: Age of mother, if the age of Smiti is 1/7th of her mother's age and after 5 years Smiti's age will be 12 years.

Quantity II: Age of mother, if the ratio of the ages of Sukriti and her mother is 3 : 7 and after 3 years the ratio of their ages will be 6 : 13.
 
» Explain it
E
Quantity I:
Smiti's age after 5 years = 12 years

Present age of Smiti = 7 years

Mother's age  = Smiti's age
7

Mother's age = 7 × 7 = 49 years

Quantity II:   Let Sukriti's age = 3x, Mother's age = 7x

According to the statement,

3x + 3 : 7x + 3 = 6 : 13

13 (3x + 3) = 6 (7x + 3)

39x + 39 = 42x + 18

39 – 18 = 42x – 39x

21 = 3x

x = 7

Mother's age = 7 × 7 = 49 years

Quantity I = Quantity II

Hence, option E is correct.

3
Quantity I: A bag contains 3 green, 2 yellow and 3 purple balls. Two balls are drawn at random, what is the probability that no ball is purple.

Quantity II: (7x – 8) (14x – 5) = 0

» Explain it
A
Quantity I:

Favourable oucomes = 5C= 10

Total outcomes = 8C2 = 28

Probability =  10  =  5
28 14

Quantity II:

(7x – 8) (14x – 5) = 0

7x 
– 8 = 0, 14x – 5 = 0

x =   8  ,  5
7 14

Quantity I ≤ Quantity II

Hence, option A is correct.

4
What is the area of the rectangle?

Quantity I: The area of the rectangle is equal to the area of the square whose side is 24 cm.

Quantity II: The perimeter of the rectangle is 88cm, if the ratio of the length and the breadth of the rectangle is 6 : 5.
 
» Explain it
E
Quantity I:

Area of the square = 24 × 24 

= 576 cm2

Area of the square = Area of the rectangle

Area of the rectangle = 576 cm2

Quantity II:

Length of the rectangle = 6x, Breadth = 5x

Perimeter = 88

2 (l + b) = 88

6x + 5x = 44

11x = 44

x = 4

Length = 24cm, breadth = 20cm

Area of the rectangle = 24 × 20

= 480 cm2

Quantity I > Quantity II

Hence, option E is correct.

5
Anuj can do the half of the work in 12 days and Manoj can do the whole work in 30 days.

Quantity I: In how many days will Anuj and Manoj do the whole work?

Quantity II: If Anuj starts the work and works for 4 days, after that Manoj join him, in how many days will the whole work be completed?
 
» Explain it
D
Anuj can do the half in 12 days so he can do the whole work in 24 days. Manoj can do the whole work in 30 days.

Quantity I:

Anuj and Monoj can do the whole work together =  1
1  +  1
24 30

1
5 + 4
  120

120  =  40 days
9 3

Quantity II:
Anuj's 1 day work =  1
24

Anuj's 4 day work =  4  =  1
24 6

Remaining work = 1 –  1  =  5
6 6

Anuj and Manoj can do the remaining work,
5
6
1  +  1
24 30

5
6
9
120

100 days
9

Total time =  100  + 4 =  136
9 9

Quantity I < Quantity II

Hence, option D is correct.
