Rajini spends 20% of his income on his children, 30% of the remaining on his wife and the remaining rs 1680 on repaying a loan what is the income of rajini

Answer 1

Answer:

let x be Rajinis salary

20% of x is (20/100)*x =x/5  =income spent on kids

30% of remaining is 30% of (his income - income spent on kids)

=(30/100)*x-(x/5)

=3x/10 - 3x/50

money spent on loan=1680

rajanis salary= spent on kids+spent on wife +spent on loan

      x = x/5 +( 3x/10 - 3x/50) +  1680

     upon solving equation,

     we get x= 3000 rupees
