A Certain sum of money is sufficient to pay either George’s wage for 15 days or Mark’s wages for 10 days. For how long will it be sufficient if both George and Mark work together ?

A. 5

B. 6

C. 8

D. 9

Answer : B. 6

Explanation:

The money can pay George’s wage for 15 days
1 Day = 1/15 of the money

The money can pay Mark’s wage 10 for days
1 Day = 1/10 of the money

Find the Amount of money needed if both of them worked together:
1 Day = 1/15 + 1/10
= 1/6 of the money

Number of days the money can last:
1/6 of the money = 1 day
6/6 of the money = 1 x 6
= 6 days

A alone can do 1/4th of the work in 2 days. B alone can do 2/3rd of the work in 4 days. If all the three work together, they can complete it in 3 days so what part of the work will be completed by C in 2 days ?

A. 1/12

B. 1/8

C. 1/6

D. 1/20

Answer : A. 1/12

Explanation:

A can do the total work in 8 days, and B can do it in 6 days.

Let the total work be 24 units.

Now,
A = 24/8 = 3
B = 24/6 = 4
A + B + C = 24/3 = 8

So Capacity of C = 1 unit.
In two days C will do 2 units which is 2/24th part of the total work. So 1/12th part.

Jake can dig a well in 16 days. Paul can dig the same well in 24 days. Jake, Paul and Hari together dig the well in 8 days. Hari alone can dig the well in ?

A. 48

B. 96

C. 24

D. 32

Answer : A. 48

Explanation:

As Jake , Paul and Hari can dig the well in 8 days,
Jack one day work = 1/16
Paul one day work = 1/24
Hari one day work = 1/x

Given,
(Jake, Paul and hari) 1 day work = 1/8

So, 1/16 + 1/24 + 1/x = 1/8
5/48 + 1/x = 1/8
1/x = 1/8 – 5/48
1/x = (6 – 5) / 48
= 1/48
1/x = 1/48

Therefore, Paul can finished work in 48 days.
