Question
Karan invested Rs. 45,000 in scheme 'X' and Rs. 30,000 in
scheme 'Y' on simple interest. Scheme 'X' offers 10% p.a. for 3 years and scheme 'Y' offers 8% p.a. for 6 years. What is the difference in the interest earned from scheme 'X' and 'Y'?Solution
ATQ,
We know that, simple interest = {(principal X rate X time) / 100}
So, simple interest received from 'X' = (45,000 X 0.10 X 3) = Rs. 13,500
So, simple interest received from 'Y' = (30,000 X 0.08 X 6) = Rs. 14,400
So, required difference = 14,400 - 13,500 = Rs. 900
