Answer»

QUANTITY A:

Let the marked price of shopkeeper A be RS. ‘x’ and that of shopkeeper B be Rs. ‘y’

SELLING price of shopkeeper A = (100 – 5)% of (100 – 15)% of (100 – 10)% of x = 0.95 × 0.85 × 0.9x = 0.72675x

Selling price of shopkeeper B = (100 – 30)% of y = 0.7y

? Their selling price is same,

⇒ 0.72675x = 0.7y

⇒ x = 0.963y

⇒ x = 96.3% of y

⇒ x = (100 – 3.7)% of y

∴ Shopkeeper A should mark his price 3.7% below the price of shopkeeper B

Quantity B:

3.6%

∴ Quantity A > Quantity B
