SSC CPO - 05 Oct 2023 - Shift 3 • Quantitative Aptitude • Q145

A shopkeeper marked the price as ₹15,000 on an article, and a successive discount of 5%, 10% and 20% was allowed on it. What is the selling price?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is Option 1 i.e. ₹10,260.

Single discount of two successive discounts = x + y + xy/100

⇒ - 5 - 10 + 50/100 = -15 + 0.5 = -14.5 

⇒ -14.5 - 20 + 290/100 = -34.5 + 2.9 = -31.6

[negative sign shows discount]

⇒ S.P. = 15000 × (100 - 31.6)/100

⇒ 15000 × 68.4/100

⇒ 150 × 68.4 = Rs.10260
