Find the simple interest if per six months years.

Find the simple interest if \( P=R s .500, R \) \( =2 \% \) per six months \( \& \mathrm{T}=2 \frac{1}{2} \) years.

  • A. Rs. 20
  • B. Rs. 25
  • C. Rs. 40
  • D. Rs. 50

Step-by-step solution

Given P=500, R=2% per six months, T=2.5 years. Since 2.5 years = 5 six-month periods, SI = (500 * 2 * 5)/100 = 50. Alternatively, annual rate = 4%, so SI = (500 * 4 * 2.5)/100 = 50. Thus simple interest is Rs. 50.
