ARs. 8,500/-
BRs. 15,000/-
CRs. 7,500/-
DRs. 17,000/-

Correct  answer is: Rs. 7,500/-

Explanation:

Let sum be Rs.x
According to the question,
\(\Large \frac{x \times 10 \times 1}{100}+\frac{x \times 12 \times 1}{100} = 1650\)
\(22x = \Large 1650 \times 100\)
\(x = \Large \frac{165 \times 100}{22}\)
\(=Rs.7500\)
