Answer» Let the monthly income be x All money and left money must combine to get the amount x. So, 1/4x +2/5x + 1/6x + 10000= x implies 15x + 24x + 10x - 60x = -600000 (multiplied equation by 60 on both sides)implies -11x = - 600000implies x= 55,555.5 that's his monthly income

Answer»

Let the monthly income be x

All money and left money must combine to get the amount x. So,

1/4x +2/5x + 1/6x + 10000= x

implies

15x + 24x + 10x - 60x = -600000 (multiplied equation by 60 on both sides)implies

-11x = - 600000implies

x= 55,555.5

that's his monthly income
