Nearly 1/4th of Japanese college students missed this elementary school math question – what about you?
The multiple-choice question asked was this:
What can be inferred from a sentence stating that the average height of 100 students is 163.5 cm?
(1) The total height of the 100 students is 16,350 cm.
(2) Students whose height are around 163.5 cm form the largest group among the 100.
(3) The number of students taller or shorter than the average is the same.
What is your answer? And yes, I did get this right.
Whoever thought up condition (3) is a little on the perverse side. The 100 students are all 163.5 cm. tall. The creator of this test may be a sharp mathematician, but he/she needs a few more English grammar lessons. Archibal
The 100 students all being 163.5 cm tall wasn’t even one of the choices!doug
I was never good at math so I know not
Well, an average would be the total of all the heights divided by the number of people. Since the average equaled 163.5 cm and the number of people were 100, the total must have been 163.5 cm x 100 = 16350 cm.So the correct answer was (1).doug
