  • Question
  • A certain factory employed 600 men and 400 women and the average wager was Rs. 25.50 per day, If a woman got Rs. 5 less than a man, then what are their daily wages ?


  • Options
  • A. m:25.50 w:27.50
  • B. m:27.50 w:22.50
  • C. m:26.50 w:27.50
  • D. m: 24.50 w:26.50

  • Correct Answer
  • m:27.50 w:22.50 

    Explanation

    Let the daily wage of a man be Rs. x.

    Then, daily wage of a woman = Rs. (x - 5).

    Now, 600x + 400 (x - 5) = 25.50 * (600 + 400) <=>  1000x = 27500 <=>  x = 27.50.

    Man's daily wages = Rs. 27.50; Woman's daily wages = (x - 5) = Rs. 22.50.
