Question

Ten friends planned to share equally the cost of buying a gift for their teacher. When two of them decided not to contribute, each of the other friends had to pay Rs.150 more. The cost of the gift was Rs. ____

A. 600  B. 6000  C. 1200  D. 12000

Accepted Answer

The total cost of the gift is Rs.1,200. Originally 10 friends share a cost C equally, each paying C/10. When 2 drop out, only 8 remain and each pays C/8. The increase per person, C/8 - C/10, equals the stated extra amount. Setting up and solving this equation gives the total gift cost directly.
