If daily wages of a man is double to that of a woman, how many men should work for 25 days to earn Rs.14400? Given that wages for 40 women for 30 days are Rs.21600.

  1. 12
  2. 14
  3. 16
  4. 18

Answer : 3

Solution :

Wages of 1 women for 1 day = 21600/(40*30)

Wages of 1 man for 1 day = (21600*2)/(40*30)

Wages of 1 man for 25 days = (21600*2*25)/(40*30)

Number of men = 14400 / ((21600*2*25)/(40*30))

= 144/((216*50)/(40*30)) = 144/9 = 16
