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
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 |
Hence, the number of 5 p coins = (3 x 50) = 150.

To convert them into rupees.
You can either convert rupee to paise or paise rupee to make them in the same unit.
Here, an interesting fact is that. From the given option the only divisible by 3 is 150. So without calculating also we can answer the question in quick time.

Friends it can be solved from options as:
We have to find out the number 5p coins,
So,
200/5 = 40
100/5 = 20
50/5 = 10
150/5 = 30
Therefore the answer is 150.
