A) Rs. 7668
B) Rs. 6603
C) Rs. 7240
D) Rs. 6390
E) None of these
Correct Answer: D
Solution :
| Ratio of the profits of Gina, Shrayon and Deepika |
| \[=48000\times 12:62000\times 8:80000\times 6\] |
| \[=48\times 12:62\times 8:80\times 6\] |
| \[=36:31:30\] |
| Sum of ratios \[=36+31+30=97\] |
| Deepika's share \[=Rs.\,\left( \frac{30}{97}\times 20661 \right)=Rs.\,6390\] |
