    Answer:

    €40,  €60, €30  

    Step-by-step explanation:

    • Manson’s daily wage- x
    • Male worker’s daily wage- y
    • Female worker’s daily wage- z

    Solution

    We will use the given to build equations and solve by elimination method

    We got as per given:

    • 2x=3y ⇒ y=2x/3
    • 15z=5x+3y+30 ⇒ 15z=5x+2x+30⇒ 15z-7x=30  (×5) ⇒ 75z-35x=150
    • x+y+2z=160 ⇒x+2x/3+2z=160 ⇒ 5x+6z=480 (×7) ⇒ 42z+35x=3360
    • 75z+42z=150+3360 ⇒117z=3510 ⇒ z=3510/117⇒ z=30
    • 15*30-7x=30 ⇒ 7x=420 ⇒ x=60
    • y=2*60/3 ⇒ y=40
    • Manson’s daily wage- €40
    • Male worker’s daily wage- €60
    • Female worker’s daily wage- €30
