Question

195 men working 10 hours a day can finish a job in 20 days. How many men are employed to finish the job in 15 days if they work 13 hours a day?

• A. 160 men
• B. 200 men
• C. 100 men
• D. 210 men

Answer 1

The correct option is B 200 men

Let x be the no. of men required

Days	Hours	Men
20	10	195
15	13	x

$20\times 10\times 195=15\times 13\times xx=\frac{20\times 10\times 195}{15\times 13}=200$
