math should be solved in mathematical way.
Trying to figure out which method GMAT opts for when finding the 'round' of a floating number.
Here are the two definitions i got online:
Bankers method: Round(5.5) = 5
Mathematical method: Round(5.5) = 6
Which method does GMAT use?? Is it written anywhere on OG Math??
Knowing 'round' is helpful in solving the following problem!!
The sides of a square region, measured to the nearest centimeter, are 6 centimeters long. The least possible value of the actual area of the square region is
A.36.00 sq cm
B.35.00 sq cm
C.33.75 sq cm
D.30.25 sq cm
E.25.00 sq cm[/i]
D. 5.5 x 5.5 = 30.25
