Answer 1

Answer:

Step-by-step explanation:

I think this will help you :-

1 Rupee = 100 paise

75Rs = 7500 paise

100p : 50p : 25p = 12 : 10 : 7

12*100X + 50*10X + 25*7X = 7500

1875X = 7500

X = 4

4*25*7 = 700 p

4*50*10 = 2000 p

4*100*12 =4800 p

sum of 4800,2000,700 is 7500. Just to verification

700 is the number of paise which we got adding all the 25 paise coins

so number of 25 paise coins = 700/25 = 28 coins.

Answer 2

The number of 25 p coins with Vijay are 28 coins.

Given - Ratio

Find - Number of 25 p coins

Solution - As we know, Re. 1 is 100 paise.

So, value of 1 Re. coin = 100 paise.

Total value of coins = 75*100

Total value of coins = Rs. 7500

Let the number of 100p, 50p and 25p coins be 12x, 10x and 7x.

So, forming the equation -

100*12x + 50*10x + 25*7x = 7500

1200x + 500x + 175x = 7500

1875x = 7500

$x = \frac{7500}{1875}$

x = 4

So, number of 25p coins = 7*4

Number = 28

Hence, there are 28 coins of 25p.
