the amount is 6.20rupees,convert rupees to paise 1 rupees =100 paise So on
6.20×100=620paise total amount
A.T.Q
let the coins of 25 paise be x
and the no. of 10 paise coins = (x-35)
equation
25 (x)+10 (x-35)=620paise
25x+10x-350=620paise
35x-350=620paise
35x=620+350
35x=970
x=970÷35
x=27.7
no. of 25 paise coins =27coins
no. of 10 paise coins =35-27
=8coins
