Question

B is 4/3 as efficient as A.
if A completes a work in 24 days then how many will B take independently to complete the same work.?

Answer 1

B is 4/3 times efficient as A. This means B gets the same work done faster.

If W is the work to be done

Work done by A in 1 day = (1/24)*W

Work done by B in 1 day = (4/3)*(1/24)*W=(1/18)*W

So in order to finish the work W

(1/18)*W*d =W

d = 18

He needs 18 days
