Answer 2

Let the monthly rent of the house be Rs x and the mess charges per head per month be Rs y.

According to the given conditions, we have,

x+2y=3900 (i)

x+5y=7500 .(ii)

Substracting equation (ii) from equation (i), we get

−3y=−3600⇒y=1200

Putting y=1200 in equation (i), we get x=1500

Hence, monthly rent =Rs. 1500 and mess charges per head per month =Rs. 1200
