Question

1500 soldiers in a fort have provision for 48 days.After 13 days, few soldiers join them and then the food lasts for 25 days . how many soldiers join?

Answer 1

food provided for for 1500 soldiers for 48 days

if 1 soldier eat 1 roti in 1 day 1500 eat 1500 rotis in 1 day

and for 48 days 1500 × 48 = 72000 rotis provided

till 13 days there are only 1500 soldiers

that means 1500 × 13 = 19500

the remaining food after 13 days is 52500

assume that x number of soldiers joined

that means the remaining food is for 1500 + x soldiers

52500/1500 + x = 25

52500 = 37500 + 25x

25x = 15000

x = 600

Answer 2

Answer:

1500 x 48 = 72000

1500 x 13 = 19500

72000-19500=52500

52500/1500+x=25

52500=37500+25x

25x=15000

x=15000/25

600
