Let the monthly salary be Rs x

He spent = 25% of x  on Household
 =  [tex] \frac{25}{100} x [/tex]

= x/4

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

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

                                                     = x/20

Remaining is invested in three schemes equally Rs 5600.

Total amount =  [tex] \frac{x}{4} + \frac{x}{20} + 5600 + 5600 + 5600 [/tex] 

x = [tex] \frac{6x}{20} + 16800 [/tex]

[tex]x - \frac{6x}{20} = 16800 [/tex]

[tex] \frac{14x}{20} = 16800 [/tex]

[tex]x = \frac{16800.20}{14} [/tex]

x = 24000

His salary is Rs 24000
