The line graph shows the production (in tonnes) and the sales (in tonnes) of a company.

What percentage (approximately) of the total production of the company is the total sales of the company in all the years together ? (correct to 2 decimal places)

78.44

Total production = 600 + 628 + 750 + 500 + 570 =  3048

Total sale = 450 + 525 + 500 + 400 + 516 = 2391

Required percentage = \(\frac{2391 }{3048}\) × 100

= 78.44%
