Options:

  • (A) 80
  • (B) 64
  • (C) 96
  • (D) 72

Answer Key:

A

Step-by-Step Solution & Explanation

Let values be $8k, 4k, 3k$. Number of coins: 1-Re $= 8k$; 50-p $= 4k / 0.5 = 8k$; 25-p $= 3k / 0.25 = 12k$. Total coins $= 8k + 8k + 12k = 28k = 280 \implies k = 10$. 50-paise coins $= 8 \times 10 = 80$.
