The respective ratio of Sita's Riya's and Kunal's monthly incomes is 84 : 76 : 89. If riya's annual income ₹ 456000, then what is the sum of Sita and Kunal's annual incomes? (In some cases monthly income and in some cases annual income is used).?

₹ 195000
₹ 983500
₹ 1130000
₹ 1038000

Correct Answer: ₹ 1038000

Explanation:

Let monthly income of Sita Riya and Kunal be 84k, 76k and 89k, respectively.
Given annual income of Riya = 456000
∴ Monthly income of Riya = 456000/12 = 38000
∴ 76k = 38000 ⇒ k = 500
So, the monthly income of Sita and Kunal = 84k + 89k = 173k
= 173 x 500 = 86500
Therefore, annual income = 86500 x 12 = ₹ 1038000
