| 12. | In a bag, there are coins of 25 p, 10 p and 5 p in the ratio of 1 : 2 : 3. If there is Rs. 30 in all, how many 5 p coins are there? | Answer: Option C Explanation: Let the number of 25 p, 10 p and 5 p coins be x, 2x, 3x respectively. | Then, sum of their values = Rs. | | 25x | + | 10 x 2x | + | 5 x 3x | | = Rs. | 60x | | 100 | 100 | 100 | 100 |
| 60x | = 30 | x = | 30 x 100 | = 50. | | 100 | 60 |
