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.

4 men can check exam papers in 8 days working 5 hours regularly. What is the total hours when 2 men will check the double of the papers in 20 days ?

A. 8 hours

B. 9 hours

C. 7 hours

D. 11 hours

Answer : A. 8 hours

Explanation:

    • Let a man can do 1 unit of work in 1 hour.
    • Total units of work = 4 * 8 * 5 = 160 units.
    • Now work = 2 * 160 = 320 units
    • Now 2 men work for 20 days. Let in x hours they have to work per day.
    • Now total work = 2 * x * 20 = 40x
    • 40x = 320
    • So x = 320/40
      • =

    8 hours
