B) 23 : 28 : 21
C) 28 : 23 : 21
D) 35 : 41 : 7
E) None of these
Correct Answer: A
Solution :
| Let investment of Aarti during first year \[=5x\] |
| Investment of Vinita during first year \[=7x\] |
| Investment of Kamla during first year \[=6x\] |
| Then, their investments during second year |
| \[(126\]%\[\text{of}5x):(120\]%\[\text{of}7x):(115\]%\[\text{of}6x)\] |
| \[=\left( \frac{126}{100}\times 5x \right):\left( \frac{120}{100}\times 7x \right):\left( \frac{115}{100}\times 6x \right)\] |
| \[=630:840:690=21:28:23\] |
