Question

The numbers $2.745$ and $2.735$ on rounding off to $3$ significant figures will give:

• A. $2.75$ and $2.74$
• B. $2.74$ and $2.73$
• C. $2.75$ and $2.73$
• D. $2.74$ and $2.74$

Answer 1

The correct option is D $2.74$ and $2.74$

In 2.745, the digit to be rounded off (i.e., 4) is even, hence it should be left unchanged and in 2.735, the digit to be rounded off (i.e., 3) is odd, hence it should be increased by 1, i.e., changed to 4.
