Question

540 bighas of land of an agricultural farm should be cultivated in 14 days. In the first 4 days, 5 tractors with equal capacity cultivated 120 bighas of land. How many more tractors will be needed to complete the farming work in time?​

Answer 1

Answer:

7 more tractors will be needed to complete the farming work in time.

Step-by-step explanation:

》In 4 days-----cultivated 120 bighas---- by 5

tractors

》In 1 day-----cultivated 120 bighas---- by (5×4)

tractors

》In 10 days----cultivated 120 bighas----by (5×4)/10

tractors (left time = 10 days)

= 2 tractors

Since,

Total land for cultivate = 540 bighas

Cultivated land = 120 bighas

So,

Left land = 540-120

= 420 bighas

》In 10 days--cultivated 120 bighas---by 2 tractors

》In 10 days--cultivated 1 bigha--by 2/120 tractors

》In 10 days--cultivated 420 bighas--by

(2/120)×420 tractors

= 7 tractors
