At a certain stage of a soccer tournament, the score ratio of teams A, B and C was 3:4:5. Eventually, the score ratio of A to B has doubled while the score ratio of A to C has halved. If the final score of team C was 40, what was the final score Q of team B?	Choose the correct choice:
A) 1)8	B) 2)10	C) 3)20	D) 4)40	E) 5)80
A to B = 3 : 4   So, on doubling we get 6 : 4   A to C = 3 : 5   So, on halving we get 1.5 : 5 or 3 : 10 or 6 : 20   So final ratio = 6 : 4 : 20.   If 20x = 40   4x = 8   Hence, answer is 1)8
