Answer 2

solution

let his monthly salary be x

now

expenditure on house rent=30% of monthly salary

=30%×x

=0.3x

again

expenditure on education=25% of monthly salary

=25%×x

=0.25x

again

expenditure on food=40% of monthly salary

=40%×x

0.4x

here

monthly salary=expenditure on house rent+ expenditure on education+ expenditure on food+saved salary

or,x=0.3x+0.25x+0.4x+1470

or,x=0.95x+1470

or,x-0.95x=1470

or,0.05x=1470

or,x=1470/0.05

or,x=29400

therefore his monthly salary is¥29,400.
