Let the monthly salary be Rs x

He spent = 25% of x  on Household
 =   \frac{25}{100} x

= x/4

20% of remaining on children education = 20% of x/4

Amount spent on children education =  \frac{20}{100}. \frac{x}{4}
  
                                                     =   \frac{1}{5} . \frac{x}{4}

                                                     = x/20

Remaining is invested in three schemes equally Rs 5600.

Total amount =   \frac{x}{4} +   \frac{x}{20} + 5600 + 5600 + 5600  

x =  \frac{6x}{20} + 16800

x -  \frac{6x}{20} = 16800

 \frac{14x}{20} = 16800

x =  \frac{16800.20}{14}

x = 24000

His salary is Rs 24000
