Respuesta :

Time taken for amar and bobby together to complete the remaining work is;  22 days

How to Solve Proportion?

Efficiency of amar, bobby and chandu is in the ratio 3:2:5.

Total work by Amar = 3 * 50 = 150 units

Work done by amar, bobby and chandu in 4 days = (3 + 2 + 5) * 4 = 40 units

Remaining work = 150 - 40 = 110 units

Efficiency of Amar and Bobby = 3 + 2 = 5 units

Thus;

Time taken for amar and bobby together to complete the remaining work is; 110/5 = 22 days
