Solution

Marked price of mattress = ₹ 7500

Discount d1 = 10%

Discount d2 = 20%

Price after discount d1 = `"M.P" xx ((100 - "d"_1%))/100`

= `7500 xx ((100 - 10))/100`

= `7500 xx 90/100`

= 6750

Price after second discount d2 = `"Discount price" xx ((100 - "d"_2%))/100`

= `6750 xx ((100 - 20))/100`

= ₹ 5400
