Question

Gopi sold a watch to Ibrahim at 12% gain and ibrahim sold it to John at a loss of 5% If John 10 rupees 1330 then find how much did Gopi sold it

Answer 1

gopi sold a watchr to ibrahim 20%

Let price be x

cost price + profit Percentage

x + 12%(x)

x + 0.12x

1.12x

Selling price of ibrahim to john = 1.2x

it will be the cost price of ibrahim to john

He Sold it 5% loss

cost price - loss percentage

(1.12x - 5%(1.12x))

(1.12x + 0.056x)

(1.176x)

John paid 1330

so..

1.176x = 1330

x = 1330/1.176 = 1131

cost price = 1131 = Gopi's sales price
