A bag contains ₹ 112 in the form of 1-rupee, 50-paise and 10-paise coins in the ratio 3 : 8 : 10. What is the number of 50-paise coins?
- a.112
- b.108
- c.96
- d.84
Answer: (A) 112
Take the coins as 3x, 8x and 10x; their values are 3x, 4x and x rupees, totalling 8x = 112, so x = 14. The number of 50-paise coins is 8 × 14 = 112. 84 or 96 coins of 50 paise would not make the total value ₹ 112.
