Answer 2

Answer:

The difference in the amounts contributed by 50 paisa and 20 paisa coins is 38000 paisa i.e. Rs.380

Step-by-step explanation:

A bag contains 50 paisa, 20 paisa and 10 paisa coins in the ratio 5:3:1.

Let the ratio be x

So, No. of coins of 50 paisa = 5x

Value of 5x coins of 50 paisa = 50(5x)=250x

No. of coins of 20 paisa = 3x

Value of 3x coins of 20 paisa = 20(3x)=60x

No. of coins of 10 paisa = x

Value of x coins of 10 paisa = 10x

Total amount = 250x+60x+10x=320 x

We are given that  the total amount in the bag is 640 rs i.e. 64000 paisa

So, $320 x = 64000$

$x = \frac{64000}{320}$

$x =200$

Value of 5x coins of 50 paisa = 50(5x)=250x = 250(200)=50000 paisa

Value of 3x coins of 20 paisa = 20(3x)=60x = 60(200)=12000 paisa

So, the difference in the amounts contributed by 50 paisa and 20 paisa coins = 50000 - 12000=38000 paisa i.e. Rs.380

Hence the difference in the amounts contributed by 50 paisa and 20 paisa coins is 38000 paisa i.e. Rs.380
