C Rs.4400, Rs.3200 Correct Answer Incorrect Answer
D Rs.1700, Rs.3700 Correct Answer Incorrect Answer

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
