  • Question
  • 4 goats or 6 sheep can graze a field in 50 days. 2 goats and 9 sheep can graze the field in?


  • Options
  • A. 100 days
  • B. 75 days
  • C. 50 days
  • D. 25 days

  • Correct Answer
  • 25 days 

    Explanation

    Part of field grazed by 4 goats in 1 day = 1/50
    Part of field grazed by 1 goat in 1 day = (1/50) x 4 = 1/200
    ? 4 g = 6 s [here, g = goats, and s = sheep]
    ? 1 s = (4/6) g = (2/3) g
    Now, 2 g + 9 s = 2 g + 9 x (2/3) g
    = 2 g + 6 g = 8 g
    ? 8 goats can graze the field in (1/8) / 200 = 25 days
