A and B's old ratio is (5:4) and the new ratio is (7:5:6). What will be A and B's sacrificing ratio?

Answer and explanation

Correct answer: (1:1)

The correct answer is option C, 1:1. Sacrificing share means old share minus new share, because it shows how much of an existing partner's share is given up for the incoming partner. The old ratio A:B=5:4 has total 9, so A's old share is 5/9 and B's old share is 4/9. The new ratio A:B:partner=7:5:6 has total 18, so A's new share is 7/18 and B's new share is 5/18. A's sacrifice is 5/9−7/18=10/18−7/18=3/18. B's sacrifice is 4/9−5/18=8/18−5/18=3/18. Thus the ratio is 3/18:3/18=1:1. Option A is the old ratio, not the sacrifice. Option B is part of the new ratio and ignores the amounts surrendered. Option C correctly compares equal sacrifices. Option D would mean A sacrificed twice as much as B, which the calculation disproves.
