The following bar chart shows the quantity (in million kg) of grains exported by India from 2018- 2022. By how much percentage is the minimum export less than the average export in the given period?

67.74%

Average export =   \(\frac{47000 + 59000 + 99000 + 20000 + 85000}{5}\)

=   \(\frac{ 310000}{5}\)

= 62000

Minimum export = 20000

Required percentage =  \(\frac{62000 - 20000}{62000}\) × 100

=  \(\frac{42000}{62000}\) × 100

= 67.74%
