Solution
Given, the cost price of an air-conditioner car = Rs. 15,200
Also, the amount spent for transportation = Rs. 300
And the amount spent for repair = Rs. 500
We deed to find out to make a gain of 15% what should be the selling price.
⇒ Actual cost price of the air conditioner with transportation and repair charges = 15200 + 300 + 500
= Rs. 16000
⇒ Now, we know that gain = `(("Gain"%) xx "Cost price")/100`
⇒ Gain = `(15 xx 16000)/100`
= 15 × 160
= 2400
⇒ Now, we know that Selling Price = Gain + Cost Price
∴ SP = 2400 + 16000 = Rs. 18400
Hence, for gain of 15% she should sell it for Rs. 18400
