How much worth chocolate should he buy so that he can accommodate it in Rs 100 ?

Solution -

If the VAT is added on the base price + Import Duty then

He would be able to buy chocolates worth Rs. 82.816

82.816 + Import Duty @ 15% Rs.12.422 = 95.238

Add 5% VAT on 95.238
Rs. 4.762

95.238 + 4.762 = 100
