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.

There are 2 possible answers for this question.
The answer already presented by most over here, where there are 150 5p coins.
And
20 25p coins, 100 10p coins & 300 5p coins. This solution can be validated by adding the total value of all these coins.
The method is as explained by Nithyanantham.

Let apply proportion 1 : 2 : 3.
25p : 10p : 5p,
Rs 30 = 300 p,
3/6 * 300 = 50 * 3 = 150.
25p : 10p : 5p,
Rs 30 = 300 p,
3/6 * 300 = 50 * 3 = 150.

Could you explain why we do not take the sum of ratios in the denominator i.e. (25x/100 + 20x/100 + 15x/100)/6 ?
Because in some problems they have considered the values like 150*2 + 25*2 and then have divided by sum of ratios i.e 4. Please clarify it.

25p : 10p : 5p = 1 : 2 : 3 = Rs.30.
1rs = 4 * 25p (or) 25p = 1/4.
Similarly, 10p = 1/10 and 5p = 1/20.
x/4 + 2x/10 + 3x/20 = 30.
x = 50
Answer:
25p = 50.
10p = 100.
5p = 150.
1rs = 4 * 25p (or) 25p = 1/4.
Similarly, 10p = 1/10 and 5p = 1/20.
x/4 + 2x/10 + 3x/20 = 30.
x = 50
Answer:
25p = 50.
10p = 100.
5p = 150.
