George does 3/5th of a piece of work in 9 days. He then calls Paul and they finish the work in 4 days. How long would Paul take to do the work by himself ?

A . 28

B . 32

C . 30

D . 35

Answer : C . 30

Explanation:

George 9 days work = 3/5
George 1 days work = 3/5 * 9
= 1/15.
George and Paul 4 days work = 2/5
George and Paul 1 days work = 2/5 * 4
= 1/10.
Paul 1 days work = George and Paul 1 days work – George 1 days work
= 1/10 – 1/15
= 1/30

So Paul takes 30 days to complete work.

The ratio of efficiency of A is to C is 5:3. The ratio of no.of days taken by B is to C is 2:3. A takes 6 days less than C, when A and C completes the work individually. B and C left the work after 2 days. The no of days taken by A to finish the remaining work ?

A. 4.5

B. 5

C. 6

D. 28/3

Answer : C. 6

Explanation:

    • A : C
        • Efficiency of A and C = 5 : 3
        • The Ratio of Work done is 3 : 5 = 3x : 5x
        • Given:
        • Difference between A’s and C’s work done is 6 days so,
        • 5x – 3x = 6
        • x = 3
        • Number of days taken by A = 3 * 3
        • =

      9 Days

        • Number of days taken by C = 5 * 3
        • =

      15 Days

    • B : C
        • Ratio of work done of B and C = 2:3
        • As we have calculated C’s total work done in 15 days so,
        • 3x = 15 days
        • x = 5
        • Therefore, Number of days taken by B = 2 * 5
        • =

      10 Days

        • Now we have total work done by a ,b and c in 9, 10 and 15 days respectively
        • Work done by B and C in initial 2 days = 2 * [ 1/10 + 1/15 ]
        • = 1/3
        • Thus, Remaining work = 1 – 1/3
        • =

      2/3

A do total work in 9 days so, 2/3 work is done in (9 * 2/3) = 6 days

Y can do a work in 2/3 the time it takes x, z can do same work in 3/4 time it takes y. when all three are typing the same time what is the fraction of total work does y do ?

A. 4/13

B. 8/29

C. 1/3

D. 9/23

Answer : A . 4/13

Explanation:

 

Time Taken by Y = (2 * 100) / 3
= 66.66 unit.

Time taken by Z = (3 * 66.66) / 4
= 50 unit.

Ratio of time of X, Y and Z = 100 : 66.66 : 50

Fraction of work Y do = 66.66 / (100 + 66.66 + 50)
= 0.307
= 4/13.

Babla alone can do a piece of work in 10 days ashu alone can do it in 15 days. The total wages for the work in Rs.5000. How much should babla be paid if they work together for entire duration of the work ?

A. 4000

B. 3000

C. 5000

D. 2000

Answer : B. 3000

Explanation 1:

Babla work = 1/10
Ashu work = 1/15
Total work = 1/10 + 1/15
= 5/30
= 6 days.

Total amount to be paid for Babla = 6/10 * 5000
= 3000

Explanation 2:

Money should always be divided in the inversely proportion way.
So Babla will get money = 15 / (15 + 10) × 5000
= 3000

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
