Best answer
Correct Answer - Option 2 : Rs. 28,000 and Rs. 50,000

Given:

Arun bought two mobiles for Rs. 50,000. He sold one at a profit of 25% and the other at a loss of 30%.

Formula used:

Selling price = cost price(100 + profit%)/100

Selling price = cost price(100 – loss%)/100

Calculation:

Let the cost price of first mobile be x

And the cost price of second mobile be 78,000 – x

According to the question,

The selling price of both mobile are same

⇒ x(100 + 25)/100 = (78,000 – x)(100 – 30)/100

⇒ 125 x = (78,000 – x)× 70

⇒ 195 x = 5460000

⇒ x = Rs. 28,000

Second mobile cost price = 78000 – 28000

⇒ Rs. 50000

∴ The cost price of both mobile is Rs. 28,000 and Rs. 50,000.
