Question

When 13546 is rounded off to four significant figures, it becomes :

• A. 1355
• B. 13550
• C. $1355\times {10}^1$
• D. 135.5

Answer 1

Answer: (B), (C)

The correct options are
B $1355\times {10}^1$
C 13550

$13546\approx 13550$

And, since last digit (6) is greater than 5,
So, preceding no. has to be raised by 1.
