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
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
MP - (a/100) × MP = x
MP(1 - a/100) = x
MP = x/(1 - a/100)
