1 Answer

Answer :

Let C be the wholesale price, listed Price be P. from (a), P = 1.2C
From (b), 0.9P = C + 10. Using statement (a), 1.2C = C + 10, from this we can
determine C.
From (C), we have sales price = C + 50. From this we cant determine C, even if we
combine information from other statements.
So (a) and (b) together are sufficient to answer the question.
Answer: c)
