Correct Answer – Option 2 : 36100
Given:
Two friends Amit and Rahul invested an equal amount of sum Rs. P in two different schemes.
Simple interest offered by the two schemes were at the rate 9% and 6% respectively and at the end of 2 years
Difference between the total amount received by Amit and Rahul was Rs. 2166.
Formula used:
Simple Interest = {Sum (P) × rate of interest (r) × time (t)}/100
Amount (A) = Principal (P) + Simple interest (S.I)
Calculation:
After 2 years, Rahul’s amount from first scheme
⇒ P + (P × 9 × 2)/100 = 118P/100
Rahul’s amount from second scheme
⇒ P + (P × 6 × 2)/100 = 112P/100
Difference between the amounts received by Rahul from both schemes
118P/100 – 112P/100 = 2166
⇒ 6P = 2166 × 100
⇒ P = 36100
∴ The value of P is Rs. 36100
