Answer 1

Correct Answer - Option 4 : Rs. 1038,00,0

Given:

The ratio of Sita : Riya : Kunal monthly income are 84: 76 : 89  and Riya annual income is Rs. 456000 

Let be total income of Sita and Kunal = x 

Calculation:

Ratio of annual income is  84 : 76 : 89

Applying the rule of proportion, we get

⇒ 76 : 456000 : : (84 + 89) : x 
⇒ Sum of Sita's and Kunal's annual income in value

⇒\(\frac{{456000}}{{76}} \times \left( {84 + 89} \right)\)

⇒ \(\frac{{456000}}{{76}} \times 173\) = 10380,00

∴Total annual income Sita and Kunal = 1038000
