RRB Group-D Model Paper 15 with answers for online practice

Given:
Principal = Rs. 5000
Time = 2 years
Difference between CI and SI = 32
Formula used:
Difference between CI and SI for 2 years= $\mathit{P}\frac{{\mathit{R}}^2}{{100}^2}$
Where P = principal, and R = rate
Calculation:
According to the question,
32 = 5000 × $\frac{{\mathit{R}}^2}{{100}^2}$
⇒ $\frac{{\mathit{R}}^2}{2}$ = 32
⇒ ${\mathit{R}}^2$ = 64
⇒ R = 8
∴ Rate of interest = 8%
