Question

A and B completed a work together in 5 days. Had A worked at twice the speed and B at half the speed, it would have taken them four days to complete the job. How much time would it take for A alone to do the work? ​

Answer 1

Answer:

Solution(By Examveda Team)

Assume work to be done 100%.

First case,

A + B = 1005

= 20% work done per day -------- (1)

Second case,

2A + B2

= 1004

= 25% work done per day ------ (2)

On solving equation (1) and (2), we get

A = 10 days
