Kashi purchased 2 cell phones and sold them after few months. He purchased one of them for Rs. 6000 but sold another one for Rs. 6000. In this deal he gain 12% on first cell phone and losing 4% on other. The gain or loss in whole deal is: Correct Answer Profit, Rs. 470.

Given:

The cost price of 1st cell phone = Rs. 6,000

The selling price of 2nd cell phone = Rs. 6,000

Gain% on selling 1st cell phone = 12%

Loss% on selling 2nd cell phone = 4%

Formula Used:

Profit = Selling Price - Cost Price

Cost price = (Selling price × 100)/(100 - Loss%)

Selling Price = Cost price × (100 + Profit%)/100

Calculation:

⇒ The cost price of 1st cell phone = Rs. 6,000

Selling Price = Cost price × (100 + Profit%)/100

⇒ Selling price of 1st cell phone = 6,000 × 112/100 = Rs. 6,720

⇒ The selling price of 2nd cell phone = Rs. 6,000

Cost price = (Selling price × 100)/(100 - Loss%)

⇒ Cost price of 2nd cell phone = 6,000 × 100/96 = Rs. 6,250

⇒ Total cost price of both the cell phone = Rs. 6,000 +  Rs. 6,250 = Rs. 12,250

⇒ Total selling price of both the cell phone = Rs. 6720 + Rs. 6000 = Rs. 12,720

Selling Price > Cost Price

Profit = Selling Price - Cost Price

⇒ Profit = Rs. 12,720 – Rs. 12,250 = Rs. 470.

∴ Total profit in both the deals Rs. 470

The correct option is 3 i.e. Profit, Rs. 470.
