Question

Round off the number of rides each bus can take in a week to the nearest hundred and choose the correct option.
$\begin{array}{cc}\text{Bus}& \text{Number of rides}\\ \text{A}& 162\\ \text{B}& 125\\ \text{C}& 110\end{array}$

• A. Number of rides of Bus C > Number of rides of Bus A
• B. Number of rides of Bus C > Number of rides of Bus B
• C. Number of rides of Bus A > Number of rides of Bus B
• D. Number of rides of Bus B > Number of rides of Bus C

Answer 1

The correct option is C Number of rides of Bus A > Number of rides of Bus B

$\bullet$ To find the nearest hundred, we check the digit at the tens place. If the digit is less than 5, round it down to the nearest hundred. If the digit is 5 or higher, round it up to the nearest hundred.
$\bullet$ By rounding off 162 to the nearest hundred, you get 200.


$\bullet$ By rounding off 125 to the nearest hundred, you get 100.


$\bullet$ By rounding off 110 to the nearest hundred, you get 100.


After rounding off:
$\bullet$ Number of rides of Bus A $=200$
$\bullet$ Number of rides of Bus B $=100$
$\bullet$ Number of rides of Bus C $=100$

We can observe:
Number of rides of Bus A > Number of rides of Bus B

$\bullet$ Hence, option A is the correct answer.
