Read the line graph carefully and answer the following question.

If the items manufactured in June is 20% more than that of April, then find the difference between items manufactured in June and March.
The line graph shows the number of electrical items repaired in given month.

The correct option is 17.

To find the solution, we first extract the relevant monthly data of items from the line graph titled "Items Repaired":

- March: 25 items
- April: 35 items

Step 1: Calculate the items for June

According to the problem, the number of items in June is 20% more than that in April.

$\text{Items in June}=\text{Items in April}\times (1+\frac{20}{100})$

$\text{Items in June}=35\times 1.2=42$

Step 2: Calculate the difference between June and March

Now, we find the difference between the items in June and March:

$\text{Difference}=\text{Items in June}-\text{Items in March}$

$\text{Difference}=42-25=17$

Therefore, the difference between the items manufactured (repaired) in June and March is 17.
