Answer 1

Step-by-step explanation:

Step-by-step explanation:let the amount of 25 paise coins be x.

let the amount of 10 paise coins be y.

therefore y+x=100

amount of money=16Rs=1600p.

therefore, 25x+10y=1600

5(5x+2y) =1600

5x+2y=1600/5

5x+2y=320

we know that x+y=100

by removing x+y=100

3x+100=320

3x=320-100

3x=220
