If a % is the discount per cent on a marked price x, then discount is
(a) x/a × 100
(b) a/x × 100
(c) x × a/100
(d) 100/ x × a

Solution:

Discount is always calculated on the marked price. Therefore if the discount rate is a% on the marked price x then:

Discount = a% of x

= (a/100) × (x)

✦ Try this: If a% is the discount and the discounted price is x then the marked price is:

Let the marked price be MP. Then we have:

a% of MP = discount

Discounted Price = MP - a% of MP

= x

MP - (a/100) × MP = x

MP(1 - a/100) = x

MP = x/(1 - a/100)
