Round the value 84.16 off to 2 significant digits.

Options

A84
B84.1
C85
D84.2

Correct answer

A. 84

Step-by-step solution

The given number is 84.16 . To round it off to 2 significant digits, we consider the third significant digit. The third significant digit is 1 , which is less than 5 . Therefore, the preceding digit 4 is left unchanged. The rounded off value to 2 significant digits is 84 .
