A sum of money amounts to Rs. 800 in 3 years and to Rs. 920 in 4 years at some rate of simple interest. The sum is how much?
Show answer & explanation
Correct answer: B
Explanation
Amount after 3 years = ₹800; Amount after 4 years = ₹920.
Interest for one year = 920 − 800 = 120.
Principal = 800 − (3 × 120) = ₹440.
