$<b>$
P = Rs 64,000
R = 5% p.a
= 5/2% for half yearly
T = 1 and 1/2years = n= 3 for half yearly
As we know the formula
A = P (1+ R/1//)^n
$= 64000 \times (1 + \frac{5}{2 \times 100} ) {}^{3} \\ = 64000 \times ( \frac{41}{40} ) {}^{3} \\ = \frac{64000 \times 41 \times 41 \times 41}{40 \times 40 \times 40} \\ = 68921$
Compound Interest = A - P
= 68,921 - 64,000
= 4,921

Hence Option B is your answer which is Rs 4,921.
