Question

4 tractors are required to cultivate 360 bighas of
land in 20 days. Let us find, how many tractors
are needed to cultivate 1800 bighas of land in 10
days.​

Answer 1

Answer:

4 tractors take 20 days to cultivate 360 bighas

1 tractor in 1 day cultivate 360/(4×20)=9/2 bighas

So 9/2 bighas is cultivated in 1 day by 1 tractor

So in 10 days 1 tractor will cultivate (9/2)×10 bighas=45

So in 10 days 45 bighas is cultivated by 1 tractor

So in 10 days 1800 bighas will be cultivated by

:1800/45=40 tractors
