Answer : Option D
Explanation :
Men = 30, days = 30
Total work = men * days = 30*30 = 900 units of work
ATQ,
1st 10 days work done = Men * days = 30*10= 300................ (i)
Next 10 days work done = Men * days = 25 * 10= 250.......... (ii)
Next 10 days work done = Men * days = 20 * 10 = 200......... (iii)
Next 10 days work done = Men * days = 15 * 10 = 150.......... (iv)
The total work done in 40 days = 300+ 250+ 200+ 150 = 900 units
ATQ, the total work which is 900 units should be completed in 30 days, but according to the solution, it takes 10 more days to get completed.
So, the work will be completed in 40 days.
