Question
Rs.6600 is divided into two parts such that if one part
be invested at 4% and the other at 6%, the annual interest from both the investments is Rs. 372. Find each part.Solution
Let the amount lent at 4% rate = Rs. x. Then, amount lent at 6% rate = 6600 - x So, => 4% of x + 6% of (6600 - x) = 372 => 6% of 6600 – 2% of x = 372 => 396 – 2% of x = 372 => 2% of x = 24 => x = (24/2) × 100 => x = Rs. 1200 Amount lent at 4% rate = Rs. 1200 Amount lent at 6% rate = 6600 – 1200 = Rs.5400
