Question

If a shopkeeper makes a profit of 20 percent on TV, and when a TV price decreases by 20 percent, a shopkeeper makes a profit of 20℅ even if he sells for a decrease of 400 rupees, then find the price​

Answer 1

Let the CP be Rs 100,

So the SP in first case becomes = Rs. 100– 20% of 100

=> 100–20= 80

In the case of 5% gain, SP= Rs.105

So the difference in both SP is= 105–80= 25

But the actual difference is = 400

So when the difference value is 25, then the actual value of difference = 400

when the value is 1, then the actual value = 400/25

when the value of CP is 100, then the actual value of CP is = 400/25 x 100

So the actual value of CP is = Rs. 1600
