Directions: Read the following questions carefully and choose the right answer.
1
The average number of chocolates that some number of boys have is 240 and average number of chocolates that some number of girls have is 180, . If each of the boys eat 10 chocolates then the average number of chocolates with all the students become 200. The total number of boys is what percentage of the total number of students?
» Explain it
B
Let the number of boys = x and the number of girls = y

The total number of chocolates the boys have = 240x

The total number of chocolates the girls have = 180y

If each of the boys eat 10 chocolates then the remaining number of chocolates, the boys will have = 240x – 10x = 230x

The sum of the all the chocolates = 200(x + y) = 230x + 180y

20y = 30x

x : y = 2 : 3

The reqd. percentage =  2 × 100  = 40%
5

Hence, option B is correct.

2
A, B and C start a business. A invests four times as much as B invests and the investment of C was x% less than that of B.  At the end of one – year, out of total profit of Rs. 5700, A’s share was Rs. 4000. What was the difference between B’s share and that of C’s share?
» Explain it
D
Let the investments of B = Rs. 100a then the investments of A = 4 × 100a = Rs. 400a

The investments of C = (100 – x) % of 100a = Rs. (100a – ax)

The ratio of their investments = 400a : 100a : 100a – ax = 400 : 100 : 100 – x

Let us assume that total profit = 400b + 100b + 100b – bx = 5700

A’s share =  4000  =  40  =  400
5700 57 600 – x

600 – x = 570

600 – 570 = x

x = 30

The ratio of profit = 400 : 100 : 100 – 30 = 400 : 100 : 70 = 40 : 10 : 7

The difference between B’s share and C’s share
3 × 5700  = 300
57

Hence, option D is correct.

Alternate Method:-

A's share = Rs. 4000

Therefore B's share = Rs. 1000 [ As Ratio of Investment of A : B = 4 : 1 , so the ratio of their profit will be = 4 : 1]

Therefore C's share = Rs (5700 – 5000) = Rs. 700

Difference between B's and C's share = Rs. (1000 – 700) = Rs. 300

Hence, option D is correct.
3
A container 'P' contains milk and water in the ratio of 4 : 5 respectively and another container 'Q' contains milk and water in the ratio of 3 : 2 respectively. If both the containers are emptied into a larger container R , then what would be the ratio of water and milk in the larger container?
» Explain it
B
The quantity of milk in the container P =  4
9

The quantity of water =  5
9

In the container Q,
 
The quantity of milk =  3
5

The quantity of water =  2
5

When both the container are emptied into a larger container
 
The ratio of milk to water =  ( 4  +  3 )  :  ( 5  +  2 )  = 47 : 43
9 5 9 5

So, the ratio of water to milk = 43 : 47

Hence, option B is correct.
4
Two friends Ram and Sham appear in an interview . There is 25% probability that Ram can be selected and 20% probability that Sham can be selected , then what is the probability that none of them get selected?
» Explain it
D
Ram’s probability of getting selected = 25% =  1
4

Sham probability of getting selected = 20% =  1
5

The probability of Ram not getting selected
= 1 –  1  =  3
4 4

The probability of Sham not getting selected
= 1 –  1  =  4
5 5

The probability of both not getting selected
3  ×  4  =  3  = 60%
4 5 5

Hence, option D is correct.
5
The height of a cylindrical shaped wood is 15 cm less than its circumference of the base and the curved surface area is 154 cm2 , then what is the volume (in cm3) of the cylinder shaped wood?
» Explain it
B
Let Radius = r then Circumference = 2πr cm and height = (2πr – 15) cm

Curved surface area = 2πrh = 2πr × (2πr – 15) = 154

By solving, r = 3.5 cm

Circumference of the base = 2πr cm = 2 ×  22  ×  7  = 22 cm
7 2

Height = 22 – 15 = 7 cm
The volume = πr2 h =  22  ×  7  ×  7  × 7 = 269.5 cm3
7 2 2

Hence, option B is correct.
