Hi All,
The answer choices to this question are written in such a way that you can avoid most of the 'math work' and answer this question with a bit of logic.
We're told that the price of sugar is increased by 7%. We're asked by what percent a home maker should reduce her consumption of sugar to have no extra expenditure. In real basic terms, we need to reduct the amount of sugar by a certain percent so that no extra money is spent.
Since the price of sugar increased by 7%, we'll have to decrease the consumption by a value that's relatively close to 7% (but NOT 7% exactly). Now look at the answers and really think about what they 'translate' into:
A. (700/107) % = a little less than 7%
B. (107/100) % = a little more than 1%
C. (100/107)% = a little less than 1%
D. (7/100)% = less than 1/10 of 1%
E. (100/700)% = 1/7 of 1%
There's only one answer choice that makes any sense given the situation described...
Final Answer:
GMAT assassins aren't born, they're made,
