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.

@All.
According to me, the solution is;
Rs.30 = 3000p (30X100=3000).
1:2:3 = 3000.
so to find out the number of 5 p coins:
3000X (3/6) = 500X3 = 1500.
Ans: 1500
Please tell me, where I am going wrong?

I think totally 30 Rs that is 30 one rupee so
1/6:2/6:3/6
30/6=5
5*20 25ps coin:10*100 10ps coin:15*20 5ps coin so
Ratio is 20:100:300
Answer is 300 5ps coins this is correct or wrong reply soon

Total amount according to ratio is (1x25+2x10+3x5) = 60 paise.
If 60 paise ----> 3000 paise.
Then 5 paise-----> ? (5x3000/60=50).
Hence the answer is : 50 x 3 = 150( here 3 is ratio of 5p).
If 60 paise ----> 3000 paise.
Then 5 paise-----> ? (5x3000/60=50).
Hence the answer is : 50 x 3 = 150( here 3 is ratio of 5p).

25p 10p 5p
1 : 2 : 3
If 25p*1=25p
10p*2=20p
5p*3=15p.
60p --> 30
1 --> 30/0.60p=50 piece,
So, 3---------50*3 = 150pieces.
1 : 2 : 3
If 25p*1=25p
10p*2=20p
5p*3=15p.
60p --> 30
1 --> 30/0.60p=50 piece,
So, 3---------50*3 = 150pieces.

My answer came 300 coins.
Rs. 30 = 30*100 = 3000 p.
Ratio = 1:2:3 then 3000*3/6 = 1500 p.
i.e. 1500/5 = 300.
Therefore, there are 300 5p coins.
Isn't it correct? Please explain me.
Rs. 30 = 30*100 = 3000 p.

1 Rs = 100 praise
25p,10p,5p.
Ratio = 1:2:3.
Then 25*x + 10*2x + 5*3x = 30*100.
25x + 20x + 15x = 3000.
60x = 3000.
X = 3000/60.
X = 50.
25p,10p,5p.
Ratio = 1:2:3.
Then 25*x + 10*2x + 5*3x = 30*100.
25x + 20x + 15x = 3000.
60x = 3000.
X = 3000/60.
X = 50.
