Let his total income be I.
Amount spent on house rent = I/3
Amount remaining = I - I/3 = 2I/3
Amount spent on other affairs = $(\frac{2}{3} \times \frac{{2I}}{3} = \frac{{4I}}{9})$
Remaining amount = 2I/9
Given, this amount is Rs.1200
⇒ $(\frac{{2I}}{9} = 1200)$
⇒ I = Rs. 5400
Amount spent on house rent = I/3
Amount remaining = I - I/3 = 2I/3
Amount spent on other affairs = $(\frac{2}{3} \times \frac{{2I}}{3} = \frac{{4I}}{9})$
Remaining amount = 2I/9
Given, this amount is Rs.1200
⇒ $(\frac{{2I}}{9} = 1200)$
⇒ I = Rs. 5400
