Option (a) is correct

Total students appeared = 600000

Total passed students = 40/100 x 600000 = 240000

Female appeared students = 40/100 x 600000 = 240000

Male appeared students = 600000 – 240000 = 360000

Male passed students = 50/100 x 360000 = 180000

So female passed students = 240000 – 180000 = 60000

Hence required percentage = 60000/240000 x 100 = 25%

विकल्प (a) सही है

उपस्थित होने वाले कुल छात्र = 600000

कुल उत्तीर्ण छात्र = (40/100) x 600000

= 240000

महिला उपस्थित छात्र = (40/100) x 600000

= 240000

पुरुष उपस्थित छात्र = 600000 – 240000

= 360000

पुरुष उत्तीर्ण छात्र = (50/100) x 360000

= 180000

तो महिला उत्तीर्ण छात्र = 240000 – 180000

= 60000

इसलिए आवश्यक प्रतिशत = (60000/240000) x 100

= 25%
