Sameer took a loan of Rs 10,000 at the interest rate of 12% per annum for 5 years. Show that the compound interest is greater than simple interest on the given amount.
Let the sum borrowed be Z. Then,
(Zx6x2⁄100) + (Zx9x3⁄100) + (Zx14x4⁄100) = 11400
Therefore, 3Z⁄25 + 27Z⁄100 + 14Z⁄25) = 11400
? 95Z⁄100 = 11400
Z = (11400x100⁄95) = 12000
