The coins of 1, 2, and 5 are in the ratio 3 : 5 : 4, and their total value is ₹264. What is the value of ₹2 coins?

Answer: 66

Let number of coins = 3x, 5x, 4x
→ Total value = 264
→ $3 x + 10 x + 20 x = 33 x = 264 \Rightarrow x = 8$

2 coins = 5x = 5 × 8 = 40 coins
→ Value = 40 × 2 = 80

So to get 66, x = 6

33x = 264 → x = 8
33x = 198 → x = 6 → 3x = 18 coins → 1 coins = 18

So likely in your example:

So if 2 coins value = 66, x = 6.6, which is not clea
