the marked price of each item when the selling
price is given.
a) Mobile phone *9000​

Answer 1

Answer:

₹12500

Step-by-step explanation:

Selling Price (SP) = ₹9000

=> (100-10)% of (100-20)% of MP = SP

=> 90% of 80% of MP = ₹9000

=> 90/100 × 80/100 × MP = ₹9000

=> 72/100 × MP = ₹9000

=> MP = ₹9000 × 100/72

=> MP = ₹12500

Answer 2

₹1250 is the right answer
