It is given that
Total C.P. of purse including VAT=Rs.523.80
Rate of VAT=8%
We know that
Actual cost of the purse =(523.80×100)/(100+8)
By further calculation
=(523.80×100)/108
=Rs485
Here
New rate of VAT=10%
Amount of VAT=485×10/100
So we get
=4850/100
=Rs.48.50
So the total cost of the purse =485+48.50=Rs.533.50
