- A is twice as good as workman as B and together they finish a piece of work in 18 days.
Question 1:
A is twice as good as workman as B and together they finish a piece of work in 18 days. In how many days will B alone finish the work. A. 27 days
B. 54 days
Feedback A do twice the work as done by B.
So A:B = 2:1
Also (A+B) one day work = 1/18
To get days in which B will finish the work, lets calculate work done by B in 1 day = (1/18∗1/3)=1/54
[Please note we multiplied by 1/3 as per B share and total of ratio is 1/3]
So B will finish the work in 54 days
So A:B = 2:1
Also (A+B) one day work = 1/18
To get days in which B will finish the work, lets calculate work done by B in 1 day = (1/18∗1/3)=1/54
[Please note we multiplied by 1/3 as per B share and total of ratio is 1/3]
So B will finish the work in 54 days
C. 56 days
D. 68 days
