E) None of these
Correct Answer: C
Solution :
| Let monthly income of Pooja, Prarthana and Falguni are Rs. 53x, Rs. 70x and Rs. 57x, respectively. |
| \[\therefore \] \[12\times 70x=420000\] |
| \[\Rightarrow \] \[x=500\] |
| Hence, required sum \[=(53+57)x\times 12\] |
| \[=110\times 500\times 12=Rs.\,660000\] |
