paise. Total amount is ` 6.20. Find the number of coins of each kind.

Answer 1

Answer:

18  and 17

Step-by-step explanation:

25 p coins- x

10 p coins- y

1. x+y=35 coins

2. 25x+10y=620 amount => 5x+2y=124

From first equation: y=35-x

Replacing y in the second equation:

5x+2(35-x)=124

3x=54

x=18

Then y=35-18=17

The answer is: 18 of 25p coins and 17 of 10p coins
