Read the line graph carefully and answer the following question.

Find the sum of items repaired in the month of February and April.
The line graph shows the number of electrical items repaired in given month.

The correct option is 80.

To find the sum of electrical items repaired in the months of February and April, we read the respective values from the provided line graph:
1. February: Locate "Feb" on the horizontal axis (months) and look at the corresponding height on the vertical axis. The plotted blue square lies exactly on the grid line for 45.
2. April: Locate "April" on the horizontal axis and look at the corresponding height on the vertical axis. The plotted blue square lies exactly on the grid line for 35.

Now, we calculate the sum of the repaired items for these two months:

$\text{Sum}=\text{Items in February}+\text{Items in April}$

$\text{Sum}=45+35$

$\text{Sum}=80$

Therefore, the sum of items repaired in the month of February and April is 80.
