Question

One collective farm got an average harvest of 21
tons of wheat per hectare and another collective farm
that had 12 acres of land less given to wheat, got
25 tons from a hectare. As a result, the second farm
harvested 300 tons of wheat more than the first. How
many tons of wheat did each farm harvest?
(a) 3150, 3450 (b) 3250, 3550
(c) 2150, 2450 (d) None of these​

Answer 1

Answer:

Check through options to solve. Option (a) is correct

since if the first farm harvested 3150 tons of wheat,

with an average harvest of 21 tons per hectare –

the number of hectares would be 3150/21 = 150.

The second farm would then harvest 12 hectares

less (as given in the question) - thus would harvest

138 hectares with an average output of 25 tons per

hectare. The total harvest would be in this case 138

¥ 3450 – and is 300 tons more than the first farm

as required. Hence, this answer is correct.
