Answer
SELF-PRACTICE — the source book printed no answer.
Nothing is invented here, so this question has no answer on record.
Explanation
P = ₹68000, $R=\frac{50}{3}\%$ p.a. and $T=\frac{9}{12}$ years $=\frac{3}{4}$ years. ∴ S.I. $=\left(\frac{P \times R \times T}{100}\right)=₹\left(68000 \times \frac{50}{3} \times \frac{3}{4} \times \frac{1}{100}\right)=₹8500$.
