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.

Rs.1=100p.
Rs.30=3000p,
Total Paisas inside = 3000p,
Sum of ratios= 1+2+3=6.
For the third ratio i.e for 5p, the equation will be: 3/6*3000÷ 3= 50.
Rs.30=3000p,
Total Paisas inside = 3000p,
Sum of ratios= 1+2+3=6.
For the third ratio i.e for 5p, the equation will be: 3/6*3000÷ 3= 50.

In a wallet, there are 50 p, 25 p and 1 Rs coins in the ratio 6 : 8 : 5. If the wallet contains Rs. 210 in total, find the number of 1 Rupee coins?

The main thing here is to convert the given data I to one standard. I mean its given as paisa so entire problem should be converted to paisa.

Let,
25p=1x,
10p=2x and 5p=3x.
Rs 30 = 30 * 100 = 3000p,
We know that;
1x + 2x + 3x = 3000,
x= 50.
Now.
5p= 3x.
5p= 3*50.
5p= 150.
25p=1x,
10p=2x and 5p=3x.
Rs 30 = 30 * 100 = 3000p,
We know that;
1x + 2x + 3x = 3000,
x= 50.
Now.
5p= 3x.
5p= 3*50.
5p= 150.

Whenever we perform any calculations
first of all it should be converted into same units
here,
1Rs.=100ps
? =25ps
we get 25/100

@HABIB
u must recheck your calculations...
As 25p*50= Rs.12.5
10p*100= Rs.10
5p*150= Rs.7.5
AND they all make Rs. 30......

Let real value is;
k:2k:3k.
So,
K + 2k + 3k = 300(30rupees = 300paisa).
6k = 300
k = 50
3k = 3 * 50 = 150.

25p : 10p : 5p
Coin = 1 : 2 : 3
______________
total = .25 + .20 + .15 = .60
5p = 30x3x100/60.
= 150 coins.
Coin = 1 : 2 : 3
______________
total = .25 + .20 + .15 = .60
5p = 30x3x100/60.
= 150 coins.

25:10:5= cancel by 5 you get 5:2:1.
Add 5+2+1=8 and add all the coins 25+10+5=40.
40/8=5.
5*30(30p given) =150.
Add 5+2+1=8 and add all the coins 25+10+5=40.
40/8=5.
5*30(30p given) =150.
