Correct Answer: INR 8,000


Solution : Let the money lent be INR $P$.
Rate of interest, $R$ = 10% per annum
Time, $t$ = 1 year 9 months
Compound interest = INR 1,460
$10\% \; \text {of} \;P + \frac{P\times 10\times 9}{100\times 12} + 10\% \; \text {of} \frac{ \;P\times 10\times 9}{100\times 12}=1460$
⇒ $0.1P + 0.075P+0.0075P=1460$
⇒ $0.1825P = 1460$
⇒ $P =\frac{1460}{0.1825}=8000$
Hence, the correct answer is INR 8000.
