You can put this solution on YOUR website! a boy spend 25% of his income on house rent 60% of remaining on household expenditures. if he saves 2100 what is his total income?
--------
Let "x" be his total income.
Equation:
x = 0.25x + (0.6)(0.75x) + 2100
-------
0.75x = 0.6(0.75x) + 2100
0.4(0.75x) = 2100
-------
0.3x = 2100
x = 2100/0.3
x = 210000/3
x = $70,000
