Question

A man divides ₹10000 into two parts. He lends the first part at 6% and the second at 8% per annum, both for 1 year. If the total interest is ₹720, how much did he lend at 6%?

Accepted Answer

4000. Let x at 6%, (10000−x) at 8%. 0.06x + 0.08(10000−x) = 720 → 0.06x + 800 − 0.08x = 720 → −0.02x = −80 → x = 4000. So ₹4000 at 6%.
