If 378 coins consist of rupees, 50 paise and 25 paise coins, whose values are in the ratio of 13 : 11 : 7, the number of 50 paise coins will be :
-
- 132
- 128
- 136
- 133
Correct Option: A
The ratio of values of rupee,
50 paise and 25 paise coins = 13 : 11 : 7
∴ Ratio of their numbers
= 13 × 1 : 11 × 2 : 7 × 4
= 13 : 22 : 28
Sum of the ratios
= 13 + 22 + 28 = 63
∴ Required number of 50 paise coins
| = | × 378 = 132 | |
| 63 |
