100 soldiers — 10days
After two days, food is left for 8 days
100 soldiers → 8 days
60 more joins them
160 soldiers → x days
Since the amount of food is not changed, amount of food consumed by 100 soldiers in 8 days is equal to food consumed by 160 soldiers in x days.
Definitely x will be less than 8.
Since no. of soldiers increase no of days decrease.
100*8 = 160*x
800 = 160*x
800/ 160 =x
80/16 =x
x = 5
