Question

the market price of watch Rs 800 gives to success discount on sales watch Rs 612 1st discount 10% II discount is second discount is

Answer 1

market price of watch = ₹800

selling price = ₹612

first discount = 10%

= 10% of 800 = ₹80

price of watch after giving first discount

= ₹800 - ₹80 = ₹720

let the 2nd discount be 'x%'

since , selling price after giving 2 successive discount = ₹612 , so then

720 - x% of 720 = 612

x% of 720 = 108

0.01x × 720 = 108

7.2x = 108 => x = 15

Answer: second discount = 15%
