Question

waheeda bought an air cooler for rs 3300 including a tax of 10% find the price of air cooler before VAT was added

Answer 1

Let the cost of air cooler before VAT added be Rs x
VAT = 10% of x = 0.1x
Cost after VAT added = x + 0.1x = 1.1x
But given cost = Rs 3300
1.1x = 3300
x = 3300/1.1
x = 3000
Price of the cooler before VAT added = Rs 3000
