Question

A shop allows a discount of 10% to its customer and still gains 20%. Find the Marked price of an item which costs Rs. 540 to the shopkeeper.

Answer 1

Shop gains 20%
So, the item is sold at 540 + 540 × 20/100
= 540 + 108
= 648

The shop gives 10% discount
So, 648 is the remaining 90%
So, 100% = 648/90 × 100
= 720
