SSC CHSL 2025 PYQ — Question 55

Principal = ₹8000
Rate = 20% per annum
Time = 1 year 6 months = 3 half years
According to the formula:
$A = P \left( 1 + \frac{R}{2 \times 100} \right)^{2n}$
Half yearly rate= 20/2= 10%
$A = 8000 \left( 1 + \frac{10}{100} \right)^3$
= 8000(1.1)³
= 8000 × 1.331
= 10648
Compound interest = 10648 − 8000 = ₹2648
