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

Answer: (D)

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 $4$.
