Question
Rs.7600 is divided into two parts such that if one part
be invested at 4% and the other at 5%, the annual interest from both the investments is Rs. 336. Find each part.Solution
Let the amount lent at 4% rate = Rs. x. Then, amount lent at 5% rate = 7600 - x So, => 4% of x + 5% of (7600 - x) = 336 => 5% of 7600 – 1% of x = 336 => 380 – 1% of x = 336 => 1% of x = 44 => x = (44/1) × 100 => x = Rs. 4400 Amount lent at 4% rate = Rs. 4400 Amount lent at 5% rate = 7600 – 4400 = Rs.3200
