Question

a dealer losses 15% if he sell his goods for rupees 680 what price he sell to gain at 15%

Answer 1

selling price = 680 rupee

dealer loss = 15%

let cost price = x

S P = ( x- 15% /100) x

S P = 85/100

x × 85 /100 =680

x= 680 ×100 /85

cost price = 800 rupee

for profit = 15%

S P = (x+15%/100)

S P = 115%/100

S P = 800 × 115%/100 = x

x= 800 × 115 /100

S P = 920 rupee

Selling price of goods should be 920 rupee to gain 15%
