Rita bought a television set with 20% discount on the labelled price. She made a profit of ₹ 800 by selling it for ₹ 16800. The labelled price of the set was

₹ 10000
₹ 20000
₹ 20800
₹ 24000

Correct Answer: ₹ 20000

Explanation:

Let labelled price of TV = ₹ R
∴ SP of the TV = [R x (100 - 20)] / 100 = ₹ 4R/5
But 16800 - 800 = 4R/5
∴ x = (16000 x 5)/4 = ₹ 20000
