SSC CHSL - 25 May 2022 - Shift 1 • Quantitative Aptitude • Q65

A bike is purchased for ₹50,000. Its rate depreciates at 10% annually. In how many years will its value be ₹36,450?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. 3

The equation formed will be 

50000 × {1 - 90/100}n = Final value

⇒ where n is the number of years.

So, 50000 × (9/10)n = 36450

⇒ (9/10)n = 729/100

We can see, n = 3
