| The respective ratio between Sita's, Riya's and Kunal's monthly income is 84: 76: 89. If Riya's annual income is Rs. 456000, then what is the sum of Sita's and Kunal's annual incomes? (In some cases monthly income and in some cases annual income is used.) |
A) Rs. 1195000
B) Rs. 983500
C) Rs. 1130000
D) Rs. 1038000
E) None of these
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 |
| \[=12\,\,(84+89)x\] |
| \[=2076\times 500=Rs.\,\,1038000\] |
