55 men can complete a piece of work in 12 days. 15 men
started the same work and worked for 10 days, and then joined by ‘x’ more men such that the remaining work is completed in 10 days. Find the value of ‘x’.Solution
According to the question, 55 × 12 = 15 × 10 + (15 + x) × 10 Or, 660 = 150 + 150 + 10x Or, 660 - 300 = 10x Or, x = 36
