Explanation: ধরি, total members = 100. Female members = 60. Female doctors = \(50\%\) of \(60 = 30\). Female doctors \(= 2 \times\) Male non-doctors. Male non-doctors = \(30/2 = 15\). Male members = \(100 - 60 = 40\). Male doctors = Male members - Male non-doctors = \(40 - 15 = 25\). Total doctors = Female doctors + Male doctors = \(30 + 25 = 55\). Percentage of doctors = \(55/100 \times 100 = 55\%\). None of the options is \(55\%\). Answer (E).
