A bag contains 1 rupee, 2 rupee and 5 rupee coins amounting to Rs.264. If the ratio of the number of these coins is 3:5:4, find the number of 1 rupee coins.

Correct answer: C. 24

  • A. 66
  • B. 48
  • C. 24
  • D. 8

Explanation

Let the coin counts be 3k, 5k and 4k. Their total value is 1(3k) + 2(5k) + 5(4k) rupees = 33k rupees, so 33k = Rs.264 and k = 8; the number of 1-rupee coins is 3 × 8 = 24 coins. The likely alternative is option b, 48 coins, which uses the multiplier itself rather than multiplying it by the first ratio term, 3.
