Answer:
150,200,250 units.
Step-by-step explanation:
- (^3=cube).
- let their incomes be in the ratio 3x,4x and 5x respectively.
- according to the given condition 27x^3+64x^3+125x^3=27000000
- 216x^3=27000000
- x^3=125000
- x=50
- therefore their incomes are 3*50=150,4*50=200,5*50=250 respectively.
- also you can cross check 150^3+200^3+250^3=27000000
