Number of male students who opted biology in school A = (900 × 30% × 7)/15 = 126
Number of male students who opted biology in school D = (800 × 18% × 5)/12 = 60
Number of female students who opted biology in school A = (900 × 30% × 8)/15 = 144
Number of female students who opted biology in school D = (800 × 18% × 7)/12 = 84
Male students who opted for biology in schools A and D : Female students who opted for biology in schools A and D
⇒ (126 + 60) : (144 + 84)
⇒ 186 : 228 = 31 : 38
∴ The correct answer is 31 : 38.
