Answer:
The stored food will last for 10 days.
Step-by-step explanation:
Let the number of days for which the food will last be x days
When 30 more jawans joined the camp,then total no. of jawans in the camp = 60 + 30 =90
no. of jawans no. of days
60 15
90 x
Since no. of jawans and no. of days are inversely proportional
60 : 90 : : x : 15
60 / 90 = x /15
By doing cross multiplication,
90 × x = 60 × 15
x = 900 /90 = 10
