Question

Mr Ramesh spends 25% of
his monthly salary on household expenditure, 20% of the remaining on children’s
education, and the remaining is equally invested in three different schemes. If
the amount invested in each scheme is Rs 5,600, what was the monthly salary of
Mr Ramesh?

Answer 1

 monthly salary of Mr Ramesh 28000.... 

Answer 2

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
