Question
An investor put Rs. x into Fund X and Rs. x/2 into Fund Y.
Fund X offers 4% p.a. and Fund Y offers 10% p.a. simple interest. If after 3 years the total interest from both funds is Rs. 540, what is the value of ‘x’?Solution
ATQ,
x × 0.04 × 3 + x/2 × 0.10 × 3 = 540
0.12x + 0.15x = 540
0.27x = 540
x = 540 / 0.27 = 2000
So, the value of ‘x’ is Rs. 2000
