Question

We get when 27 is rounded off to the nearest tens.

• A. 20
• B. 25
• C. 30

Answer 1

The correct option is C 30

We round off numbers as below. $$\begin{array}{cc}\text{Numbers}& \text{Rounded off to}\\ \text{0 - 4}& \text{0}\\ \text{5 - 9}& \text{10}\end{array}$$
The number 27 has 7 in ones place which is greater than 5
We round it off to 30.
