Question

Aman and Raman are two workers. Working together they can complete the whole work in 10 hours. If the Aman worked for 2.5 hours and Raman worked for 8.5 hours, still there was half of the work to be done. In how many hours Aman working alone, can complete the whole work?​

Answer 1

Answer: Given:

Time to complete the work by Aman and Raman together = 12 days

Time to complete the work by Aman alone = 15 days

Formula used:

Efficiency = (Work done)/Time

Calculations:

Aman and Raman together can do a work in 10 days.

So, Part of work Aman and Raman can do in 1 day = 1/10

Aman alone can do the work in 12 days

So Part of work Aman can do in 1 day = 1/12

Part of work Raman can do in 1 day = (1/10) - (1/12)

Part of work Raman can do in 1 day = (6 - 5) / 60 = 1/60

∴ Raman alone can do the work in 60 days
