Question

by seeling a table for r 350, rajesh lost 12.5% of the cost price.findthe gain percent if he were to sell the table forr 440.

Answer 1

let cost price = x

loss = 12.5% of x = 12.5x/100

selling price = cost price - loss

Rs 350 = x - 12.5x/100

⇒ 35000 = 100x - 12.5x

⇒ 87.5x = 35000

⇒ x =  35000/87.5 = Rs 400

cost price of table = 400

if selling price = 440 , then

gain% = (selling price - cost price) * 100 / cost price  = (440 -400) × 100/400

         =  4000/400 = 10%

so if selling price was 440 , gain % = 10%
