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 answer is 17.

By analyzing the provided line graph, we can read the number of items repaired for each month:
- March: 25
- April: 35

We are given that the number of items in June is 20% more than that of April. We calculate the items in June as follows:

$\text{Items in June}=35\times \left(1+\frac{20}{100}\right)$

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

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

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

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