Answer:
Correct Answer: D
Solution:
- Let Sita’s, Riya’s and Kunal’s monthly income be Rs. 84x, Rs. 76x, Rs. 89x, respectively.
$ \therefore $ $ 76\times 12\times x=456000 $
$ \Rightarrow $ $ x=\frac{456000}{76\times 12}=500 $
Hence, total annual income of Sita and Kunal
$ =12(84+89)x $
$ =2076\times 500=Rs.1038000 $
