Explanation:

Ratio of wages of 20Men, 30Women and 48Children
=3*20 : 2*30 : 1*48
=5: 5: 4.
Wages of 20 Men per week =5/14 *840=Rs300.
Then wages of a man per week =300/20=Rs15.
Similarly, wages of a woman per week=Rs10
wages of a children per week=Rs5.
Total wages per week =10*15 + 10*20 + 5*30
=150+200+150
