let no. of 25 paise coin=x and 10 paisa=y
25x+10y=6.20_eq1
x+y=35_eq2
=x=35-y
by putting value of x in eq 1 we get
25(35-y)+10y=6.2
from this eq u will get value of y and then subtract it from 35 to get valiue of x
25x+10y=6.20_eq1
x+y=35_eq2
=x=35-y
by putting value of x in eq 1 we get
25(35-y)+10y=6.2
