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. .<\/p>\n\n\n\n
(A) 666<\/p>\n\n\n\n
(B) 3000<\/p>\n\n\n\n
(C) 6000<\/p>\n\n\n\n
(D) 12000<\/p>\n\n\n\n
Ans:(C) 6000<\/p>\n\n\n\n
Solution:<\/p>\n\n\n\n
Let share of each student = x<\/p>\n\n\n\n
Since cost of gift will be same in both situation, therefore,<\/p>\n\n\n\n
\u2192 10*x = 8*(x + 150)<\/p>\n\n\n\n
\u2192 10*x = 8*x + 8*150<\/p>\n\n\n\n
\u2192 2*x = 8*150<\/p>\n\n\n\n
\u2192 x = 8*150 \/ 2<\/p>\n\n\n\n
\u2192 x = 600<\/p>\n\n\n\n
Therefore, cost of gift is, 10*x = 10*600 = 6000<\/p>\n","protected":false},"excerpt":{"rendered":"
