Question
40 men are engaged to dig a 4 km long drainage channel.
After working 12 days, only 1/2 of the work is done. Then 8 more men are employed. Find the number of days required to complete the remaining work.Solution
ATQ, Let the number of days to complete the remaining work be x. (40 × 12) / (1/2 × 4) = 48x / (1/2 × 4) (40 × 12) / 2 = 48x / 2 240 = 24x x = 10 days
