Question

Ram took a loan of 40,000 rupees from his friend at 10 percent per annum for 2

years.After 2 years he returned an amount of 20,000 rupees and a watch​

Answer 1

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
