Answer 2

SOLUTION :-

Principal (P) = Rs 2000

Rate of Interest (R) = 4 whole $\frac{1}{2}$ % per annum = 4.5 % p.a

Time (T) = 6 months = $\frac{6}{12}$ years = $\frac{1}{2}$ years = 0.5 years

To be found :-

The Simple Interest (S.I)

S.I = $\frac{P \times R \times T }{100}$

S.I = $\frac{2000 \times 4.5 \times 0.5}{100}$

S.I = Rs 45

Hence

The Simple Interest (S.I) = Rs 45
