​

Answer 1

Answer:

Rs. 9120 is your yearly income.

Step-by-step explanation:

Total amount spent within those 7 years = Rs. 8400

Debt incurred = Rs.880 x 9

                        = Rs.7920

Your yearly income = Rs.7920 + Rs. 1200

                                 = Rs.9120

Answer 2

Answer:

Rs.1020 (yearly encome)

Step-by-step explanation:

Let , Yearly income = x

So, from first condition we get

Debt = 1200 × 7 - 7 x ,

Debt = 8400 - 7 x --- ( 1 )

And from second condition we get

Amount ( Same as debt in equation 1 ) = 9 x - 9 × 880 = 9 x - 7920 , From equation 1 we get

9 x - 7920 = 8400 - 7 x ,

16 x = 16320 ,

16 x = 16 × 1020 ,

x = 1020

Therefore,

Yearly income = Rs . 1020
