Question

the rate at which a works is 50% more than at which b works . if a works for 10 days and then b joins him and together they complete the job in 6 days after which a leaves and remaining work is completed by b .find the time taken by a alone to do the work​

Answer 1

Answer:

9 days.

Efficiency ratio of A and B is: 150:100 or 3:2; Time ratio is 2:3

B completed a certain part of the work in 15 days. The remaining work was done by A alone in 8 days. Also, the remaining work could have been done by B in 8+4=12 days. It implies that B alone can complete the work in 15+12=27 days. therefore, B will take 27/3=9 days to complete 1/3rd of the work.
