Q. A man had 16000 Rs., part of which he lent at 4% and the rest at 5% per annum simple interest. If the total interest received was 700 Rs. In one year, the money lent at 4% per annum was :
Answer: 10000 Rs
Notes: Let the sum lent at 4% = Rs. x ∴ Amount at 5% = 16000 - x According to the question, $latex \frac{x\times 4\times 1}{100}+\frac{(16000-x)\times 5\times 1}{100} = 700&s=1$ $latex => 4x + 80000-5x = 70000$ $latex => x = 80000 - 70000 = 10000$ Hence option [C] is correct answer.
