Answer 1

Answer:

1,92,000 ( choice is 2)

Step-by-step explanation:

let ₹I and ₹e be the monthly Income and monthly expenses of Raju.

Given, (5/4)i -2e = 12000.

From:

I - e = (5/4)I - 2e = 4I - 4e = 5I - 8e = I = 4e.

I - e = 3e = 12000

= e = 4000

monthly income of Raju = I = 4e = 4×4000 = 16000.

Annual income of Raju = 12 × 16000 = 1,92,000.
