Discount and marked price — Quantitative aptitude for kids

The marked price is the price on the tag. A discount is taken off the marked price, and you pay the rest. Two discounts one after the other are less than their sum, because the second works on the already reduced price.

The method

Marked price is 100% — “the discount is a percent of the marked (printed) price”

  1. Discount = d% of marked price; you pay marked price − discount.
  2. Discount % = discount ÷ marked price × 100.
  3. Marked price from the price paid: price × 100 ÷ (100 − d).
  4. Two discounts a% and b% = one discount of a + b − (a × b) ÷ 100.

Use it for: Sales and festive offers, comparing deals online, and commercial maths in Class 8.

🧮 Check your own sums with the free Discount calculator — it shows the working.

Worked example: A school bag is marked at ₹1200. The shop gives a 25% discount. How much do you pay (in ₹)? → 900

  1. Discount = 25% of ₹1200 = ₹300.
  2. You pay 1200 − 300 = ₹900.

Check: ₹900 is 75% of ₹1200 (900 × 100 ÷ 1200 = 75) ✓
