Answer 1

for tree plantation 30 workers dig 20 pits in 40 days. If 40 worker have to dig 30pits , how many day will be required

Answer 2

consider the workers as x then

30x = 20pits in 40 days

30x = 2 pits in 4 days = 30 workers take 2 days for one pit to dig

if 30 workers take 2 days for one pit then

1.3 × 30 = 30 ÷ 1.3 = your answer

40x = 23.07 days

40 workers take 23 days to dig 30 pits
