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

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
