Question
Rahul invested Rs. ‘x’ at 13% p.a. and Rohit
invested Rs. (x + 300) at 12% p.a. If the interest after 3 years is Rs. 1755, find the value of ‘x’.Solution
According to the question,
(x × 0.13 × 3) + {(x + 300) × 0.12 × 3} = 1755 Or, 0.39x + 0.36x + 108 = 1755 Or, 0.75x = 1647 Or, x = 1647 / 0.75 = 2196 Or, x = Rs. 2196
