  • Question

  • Options
  • A. 175
  • B. 145
  • C. 165
  • D. 135

  • Correct Answer
  • 175 

    Explanation

    Let the number of males be 'M'
    Let the number of females be 'F'
    From the given conditions,
    (F-15)=2M.....(i)
    F=5(M-45).....(ii)
    By solving the equations (1) & (2) we get M = 80
    Then substitute M = 80 in (1)
    F = 2M + 15
    F = 2 x 80 + 15
    => F = 175
    Therefore, number of males = 80 and females = 175 in the party.
