Question

The yield of wheat from 8 hectares of land is 360 quintals. Find the number of hectares of land required for a yield of 540 quintals.

Answer 1

Given, the yield of wheat from 8 hectares of land is 360 quintals.

i.e. 360 quintals wheat is yielded by = 8 hectares.

Using unitary method in which first we find the value of one unit and then the value of the required number of units.
1 quintal wheat is yielded by = $\frac{8}{360}$ hectares.
540 quintals wheat will be yielded by = $\frac{8}{360}\times 540=12$ hectares.
Hence, 540 quintals will be yielded by 12 hectares.
