This is a simple question, but
be careful on simple questions not to fall into traps. Read carefully and ensure you know what you're solving for.
In particular, note here that the question is asking for the item purchased
at the greater dollar value.Statement 1:We're given the
percent discount for the tie, but nothing about the belt. The purchase price of either item could be anything, so either item could have the higher purchase price.
Insufficient.Statement 2:We're given the
percent discount for the belt, but nothing about the tie. The purchase price of either item could be anything, so either item could have the higher purchase price.
Insufficient.Together:Now we have information for both items, so the "real question" is whether the statements are sufficient together. But the information you're given only references
percentage discounts, not
dollar amounts (which is what the question asks you to compare). So the purchase price of either item could still be anything, and either item could have the higher purchase price.
Insufficient. The answer is E.If you were unsure, think of extremes. If, before the discounts, the tie cost $1,000 and the belt $1, the shopper clearly paid more for the tie (no need to actually calculate the discounts). And if you flip it, so that the belt cost $1,000 and the tie $1, the shopper clearly paid more for the belt.
The trap is to think that because the tie has the smaller percentage discount, the shopper must have paid more.
Always know what you're solving for before you go to the statements. And before you finalize your answer, make it a habit to check that you've answered the right question. Then you will avoid making careless errors and falling into traps.
