Step-by-step explanation:

let raj's income be x

his savings =3600

house rent =20% of x =x/5

left=x -x/5 =4x/5

house hold = 70/100*4x/5

=14x/25

savings = 3600

x= x/5+14x/25 +3600

-3600=19x/25-x

3600*25/6=x

x=15000

Answer 2

Answer:

His total income of per month is ₹15000.

Step-by-step explanation:

Let the total income be ₹x.Then,

Amount spend on house hold rent=20% of x.

20% of x

= 20/100×x

= x/5

Rest amount = x-x/5

= 4x/5

expenditure on household= 70% of 4x/5

= (70/100)×(4x/5)

= 28x/50

Save amount = 4x/5-28x/50

= 12x/50

Now,

12x/50 = 3600

x = 15000
