0. 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. ___________.

  • Option : C
  • Explanation :
    Let share of each student = x
    Total cost of gift = 10 × x
    x = 8(x + 150)
    x = 600
    Total cost = 10 × 600 = 6000
