Step-by-step explanation:
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
