At a recent sale, Harue bought various numbers of 5 types of school supplies - markers, pens, pencils, erasers, and notebooks - each advertised with a different pricing strategy. Harue bought 4 markers for the price of 3, 3 pens for the price of 2, 5 pencils for the price of 3, 2 erasers for the price of 1, and 5 notebooks for the price of 2. One of the 5 types of school supplies was advertised as "Buy one, get one at 50% off." Which type?
A. Markers
B. Pens
C. Pencils
D. Erasers
E. Notebooks
A. Markers
B. Pens
C. Pencils
D. Erasers
E. Notebooks
Buy one, get one at 50% off means Buy one piece at FULL price and get second at HALF price.
Normally he would have got half the item for half the price but now he gets a full piece.
Thus, he buys two at the price of one and half pieces.
Ratio is 2:1.5 or 4:3 or 8:6 or 12:9 and so on.
Check if you have any ratio out of the above.
A. Markers => 4:3
B. Pens => 3:2
C. Pencils => 5:3
D. Erasers => 2:1
E. Notebooks => 5:2
Only A matches.
