she has 7500 coines of 20 paise and 15000 coines of 10 paise because let no. of 20 paise=x and no. of 10 paise=y
then both are equal in no. so x=y and total is 300 RS so x+y=300 RS and 1 RS=100 paise Soo
x+y=30000...
now from 1st equation x+x=30000 so x=15000 and y=15000
then both are equal in no. so x=y and total is 300 RS so x+y=300 RS and 1 RS=100 paise Soo
x+y=30000...
now from 1st equation x+x=30000 so x=15000 and y=15000
