after allowing 20% discount on the Mark price and then levying VAT 10%, a mobile set was sold. if buyer had paid Rs. 320 for VAT, how much would he have got the discount

            He has got Rs. 800 discount

Step-by-step explanation:

x -  the price

20%x = 0.2x  - the discount

x-20%x = 80%x = 0.8x  - price after discount

10%•0.8x = 0.1•0.8x = 0.08x   - VAT to pay

0.08x = 320

x = 320:0.08 = 4000

0.2x = 0.2•4000 = 800

₹800

Step-by-step explanation:

Let the Marked price be 100

Discount = 20% = 0.2

Discounted price = 100 - 0.2*100 = 100 - 20 = 80

Rate of VAT = 10% = 0.1

Amount of VAT = 0.1*80 = 8

Since, 8 = ₹320

Therefore, 100 = 320*100/8 = 40*100 = ₹4000

Amount of Discount = 0.2*4000 = ₹800
