If the integer x is rounded to the nearest hundred, the result represents a 66 2/3 % increase over the value obtained when x is rounded to the nearest ten. which of the following is a possible value of x?

A. 64

B. 67

C. 99

D. 133

E. 147

What is 99 is rounded to nearest ten? Also what is 133 rounded to nearest ten & hundred?

We have to check options 1 by 1.

64 rounded to nearest hundred = 100

64 rounded to nearest ten = 60

now difference = 40

the result represents a 66 2/3 % increase over the value obtained when x is rounded to the nearest ten.

therefore 40/60)*100 = 66 2/3 ==>this is the answer.

99 rounded to nearest ten = 100

133 rounded to nearest ten = 130

133 rounded to nearest hundred = 100

hope this helps
