Question

If Anna exercises for $45$ minutes per day, then for how many minutes did she exercise in the month of march?

• A. $1,305$ minutes
• B. $1,395$ minutes
• C. $1,593$ minutes

Answer 1

The correct option is B $1,395$ minutes

Number of minutes that Anna exercises for everyday $=45$ minutes
Number of days in March $=31$
Number of minutes Anna exercised for in March is $45\times 31$

This can be evaluated as follows:
First we multiply $45$ with the ones place digit of $31$


Then we multiply with the tens place value of $31$


Now, we will do the addition:
$45\times 31=1395$

Total number of minutes exercised by Anna is $=1395$
