Q. 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) 666
(B) 3000
(C) 6000
(D) 12000
Ans:(C) 6000
Solution:
Let share of each student = x
Since cost of gift will be same in both situation, therefore,
→ 10*x = 8*(x + 150)
→ 10*x = 8*x + 8*150
→ 2*x = 8*150
→ x = 8*150 / 2
→ x = 600
Therefore, cost of gift is, 10*x = 10*600 = 6000
