Question

In a garrison there are provisions for 1500 soldiers for 40 days when consumption
per day per soldier is 800 grams. If 500 more soldiers join and consumption per
day per soldier is increased by 200 grams, how long will the provision last.​

Answer 1

Answer:

80

90

100

120

Answer : 

C

Solution : 

Let the consumption of each person per day =K kg. 

Let the required time be x. 

Quantity of food available in the fort =(K)(1500)(90)=(K)(1500)(90) kg. 

⇒(K)(1500)(90)⇒(K)(1500)(90) 

⇒(K+50100(K))(1500−600)(x)⇒(K+50100(K))(1500-600)(x) 

x=(2)(1500)(90)(3)(900)=100x=(2)(1500)(90)(3)(900)=100.
