Question

If 10 men can survive for 24 days on 15 cans of rations, how many cans will be needed for 8 men to survive for 36 days?

Answer 1

10 men can survive for 24 days with 15 cans of ration
so , 1 man can survive for 1 day with 15/(10*24) cans of ration
so, 8 men can survive for 36 days with (15*8*36)/240 = 18 cans of raion

Answer 2

18 cans

Explanation:

Given : 10 men can survive 24 days on 15 cans

To find : how many cans for 8 men can survive for 36 days

Solution : 1 men can survive 1 day on= 15/ 10×24 = 15/240 cans

8 men can survive 1 day = 8×15/240= 1/2 cans

8 men can survive for 36 days = 36/2= 18 cans

therefore, 8 men can survive for 36 days = 36/2= 18 cans
