Question

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

Answer 1

Given,

Tax = 10%

CP = Rs. 3300

Let the MP be x.

So,

CP = {(100 + tax%) / 100} × MP

⇒ Rs. 3300 = {100 +10/100} × MP

⇒ Rs 3300 = 11/10 × MP

⇒ (Rs 3300 × 10)/11 = MP

⇒ MP = Rs 3000.

So, the price of air cooler before the tax was added was Rs 3000
