Question
30 labourers are assigned to dig a 4 km canal. After 12 days, only half of the work is over. Later, 6 more labourers are added. Find in how many days the remaining work will be completed.
Solution
ATQ, Let the number of days to complete the remaining work be x. (30 × 12) / (1/2 × 4) = 36x / (1/2 × 4) (30 × 12) / 2 = 36x / 2 180 = 18x x = 10 days
