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

8/36 : 24/30 : x/80

more men ,more days than more hectares.......so wl apply indirect approach
x=(36 * 24 * 80) / (30 * 8)
x=288

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.

8 men can reap 80 hectares in 24 days .

So one guy can reap 10 hectares in 24 days .

One guy can reap 10/24 = .416 hectares in 1 day .

Answer = .416* 30 * 36 = 450 hectares.

8 Men work in 24 days:- 80
1 Men work in 24 days:- 80/8 = 10
1 Men work in 1 days:- 10/24
1 Men work in 30 days:- (10/24)*30
36 Men work in 30 days:- ((10/24)*30)*36 = 450

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
=450

ans is simple
1 men  1hec can in =80/24*8
so 36 men in 30 day will reap=80*36*30/24*8=145 hec
