Question

A field can be ploughed in 14 days. If 20 hectares of land is ploughed more daily , the work will be finished in 10 days . Find the area of the land which can be ploughed daily. Also, find the area of field.
​

Answer 1

Answer:

Total area of land is 700 hectares and the area of land which is ploughed everyday is 50 hectares

Step-by-step explanation:

let's assume area of field be F

Area of field ploughed in 1 day will be F/14

F/14 + 20 = F/10

F/10 - F/14 = 20

14F - 10F whole divided by 140 is equal to 20

(14F - 10F/140)

4F = 20*140

F = 20*140/4

F = 700 hectares

so the area of field is 700 hectares

the area of land ploughed daily = F/14

700/14 = 50 hectares

the area of land ploughed daily is 50 hectares
