Question

what sum of money at 12%p.a for 3 years will produce the same simple interest as rs 2250 at 10% p.a for 4 years​

Answer 1

Step-by-step explanation:

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
