  • Options
  • A. 32
  • B. 36
  • C. 34
  • D. Cannot be determined

  • Correct Answer
  • 34 

    Explanation

    Let hens = H, goats = G
    According to the question,
    H + G = 90 ...(i)
    2H + 4G = 248 ...(ii)
    On multiplying Eq. (i) by 2 and subtracting from Eq. (ii) , we get
    2H + 2G = 180
    2H + 4G = 248
    -------------------
    -2G = -68
    ? G = 34
