Question

A certain sum of money at S.I. amounts to rs. 500 in 3 years and to rs. 600 in 5 years then the principal amount is?

Answer 1

Answer:

350

Step-by-step explanation:

p [ 1 + 3r/100] = 500 --(1

p [ 1 + 5r/100] = 600. --(2

on deviding (1) by (2) ,we have

6 ×(100 +3r) = 5 × (100+ 5r)

7r = 100 => r = 100/7%

p (1+ 3×100/7/100) = 500

10p = 3500 => p = Rs 350
