Anil works for 8 straight days and rest on the 9th day. If he starts his work on Monday, then on which day he gets his 12th rest day?

• Thursday

• Tuesday

• Wednesday

• Friday

Answer explanation

Anil works for 8 days and rests on 9th day. In total 9 days are to be processed 12 times = 12 * 9 = 108.
If we calculate according to the week, we get 108 / 7 = remaining 3 days. So if Anil starts working on Monday, he will rest on third day of the week which is Wednesday.

A team of 11 is needed to be formed who are to be selected from 5 men and 11 women, with the restriction of selecting not more than 3 men. In how many ways can the selection be done?

• 1121

• 1565

• 1243

• 2256

Answer explanation

Selecting 0 men and 11 women = 5C0 11C11 = 1
Selecting 1 men and 10 women = 5C1 11C10 = 55
Selecting 2 men and 9 women = 5C2 11C9 = 10 55 = 550
Selecting 3 men and 8 women = 5C3 11C8 = 10 165 = 1650
So total number of ways = 1650 + 550 + 55 + 1 = 2256 way

Let a number ‘x’ when divided by 406 leaves a remainder 115. What will be the number when the number is divided by 29? 

• 30

• 23

• 26

• 28

The number is equal to 406 * y +115

(406 * y) + 115 = Number

(406 * y) is divisible by 29.

but when 115 is divided by 29 leaves 28 as remainder.

So, 28 is the remainder, which is the answer.

Ram will be 32 years old in eight years from now. In 4 years, Ram’s fathers age will be twice as Ram’s age and two years ago, his mother’s age will be twice as his age. What will be the present age of Ram’s father and mother? 

• Father's age = 52, Mother's age = 46

• Father's age = 46, Mother's age = 52

Answer explanation

Ram will be 32 years old in next 8 years. So his present age is 32 – 8 = 24 years old 
After 4 years Ram will be 28 years old. So his father will be 28 2 = 56 years old. 
Therefore, fathers present age is 56 – 4 = 52 years old 
Two years ago Ram was 22 years old. So his mothers age the was 22 2 = 44 years old 
Therefore mothers present age is 44 + 2 = 46 years old.

A takes 3 days to complete a work while B takes 2 days. Both of them finish a work and earn Rs. 150. What is A’s share of money?

• 70

• 30

• 60

A completes 1/3rd of work in one-day and B completes 1/2 of work in one day. So the ratio of there work is:
A:B = 2:3
So A’s share = (2/5)*150 = 60 rupees

Aman completes a journey in 10 hours. He travels the first half of the journey at the rate of 21 km/hr and the second half at the rate of 24 km/hr. Find the total journey in km. 

• 220 km

• 234 km

• 230 km

• 224 km

Answer explanation

According to the question, 
((1/2)x)/21 + ((1/2)x)/24 = 10 
Solving this equation we get 15x = 168 20 
Further x = (168 20)/15 = 224 km.
