Question

the could do in a day what the Bullocks would take many days to do​

Answer 1

Answer:

x bullocks +y tractors can plough a field in = 8 days. , therefore

8x bullocks+8y tractors can plough a field in=1 day………………(1)

x/2bullocks +2y tractors can plough a field in= 5days. ,therefore

5x/2 bullocks+10y tractors can plough a field in =1day…………..(2)

From eqn. (1) and (2)

8x bullocks+8y tractors= 5x/2 bullocks +10y tractors

(8x-5x/2) bullocks =(10y-8y) tractors

11x/2 bullocks = 2y tractors. OR. y tractors = 11x/4 bullocks.

From eqn. (1)

8x bullocks+8.(11x/4) bullocks. Or 30x bullocks can plough = 1 day.

Thus x bullocks can plough = 30x/x = 30 days
