Study the given table and answer the question that follows. The table shows quantity of various food items used by a restaurant during four months of a year (in kg).

The quantity of wheat used in the month of July is what percentage of the total quantity of food items used in June?

$29\frac{17}{27}$%

Total quantity of food items used in June = 180 + 420 + 200 + 250 + 300

= 1350

Quantity used of wheat in July = 400

Required percentage = \(\frac{400 }{1350}\) × 100

= 29 \(\frac{17 }{27}\)%
