Hi,
A certain store has decided that it will reduce all prices based on a formula. If a price of an article costing $8 will be reduced to$x, what is the original price of an article whose price will be reduced to $3 1.x =6 2.The formula is: the reduced price equals the original price minus two. The official answer is : A Based on (1) we can make different assumptions .e.g the reduced price equals the original price minus two OR the discount percentage is 25%. Based o the former , we get 5 as the original price and based on the latter we get 4. In short (1) is not sufficient and thus A is not right. Just wondering what you guys think?

No, everybody. The answer here is B.

In 1) the formula could be anything that maps 8 to 6. Hence we have no idea what number maps to 3. (e.g. formula could be subtract 2 or could be multiply by 3/4).

In 2) the formula is given explicitly, hence 5 is the only number that can map to 3.
