By selling an object for Rs 900, a man earns a profit that is double the loss incurred when the object is sold for Rs 450. If he sells it at a profit of 20%, find the selling price of this object.

None of these

Let the loss be x

Then profit = 2x

ATQ,

Cost price ⇒ 450 + x = 900–2x

3x = 450

x = 150

Cost price = 450 + x = Rs.600

Selling price at 20% profit = C.P. × 120% = 600 × 120% = Rs.720
