Show answer & explanation
Correct answer: D
College C has 82 + 24 = 106 staff. Let C professors be P, so C lab assistants are P - 6. Then P + (P - 6) = 106, giving P = 56 and C lab assistants = 50. B lab assistants = 54 and A professors = 10, so A lab assistants = 72. Total professors are 102, so B professors = 102 - 10 - 56 = 36. The required ratio is 36 : 72 = 1 : 2.
