Madhya Pradesh Police Exam Model Paper 2

Given:
Time = 2 years
Rate = 12%
CI - SI = ₹ 46.08
Formula used:
CI - SI = Principle $\times {\left(\mathit{r}/100\right)}^2$
Calculation:
We know that -
CI - SI = Principle $\times {\left(\mathit{r}/100\right)}^2$
⇒ 46.08 = Principle $\times {\left(12/100\right)}^2$
⇒ Principle $=\left(46.08\times 100\times 100\right)/\left(12\times 12\right)$
⇒ Principle = ₹ 3200
∴ required sum is ₹ 3200.
