By Direct approach :
more men,more hectares
moredays,more hectares
so,
8 / 36 : 24 / 30 = 80 / x

x = (36 x 30 x 80) / (8 x 24)
 450

IF 8 men can reap 80 hectares in 24 days then

this is sure that 36 men can reap more than 80 hectares in 30 days so

we have greater values in nominator than denominator.

(36/8)*(30/24)*80

that is 288.

For sure.

For 1 day no.of.hectares reap is 80/24=3.333
in reaping 3.333 hectares the work divided by 8 men is 3.333/8=0.4166

this 0.4166 indicates 1 men reap in 1 day is 0.4166
 
and for 36 men and 30 days it is given by=0.4166*30*36
