a) Rs. 1700
b) Rs. 1800
c) Rs. 1900
d) Rs. 2000
Answer: d
Explanation: Let the amount invested = Rs. P
$$\eqalign{
& \frac{{{\text{P}} \times 9 \times {\text{2}}}}{{100}} + \frac{{{\text{P}} \times {\text{10}} \times {\text{2}}}}{{100}} = 760 \cr
& \frac{{ {18{\text{P + 20P}}} }}{{100}} = 760 \cr
& 38{\text{P = 76000}} \cr
& {\text{P = 2000}} \cr} $$
