Answer 2

Total number of people are C. 2000.

Given - Percentage and non vegetarian people

Find - Total number of people

Solution - Let the total number of people be x. Forming equation-

80%*x + 400 = x

80x/100 + 400 = x

Performing division

0.8x + 400 = x

400 = x - 0.8x

Performing subtraction

400 = 0.2x

x = 400/0.2

Performing division

x = 2000

Hence, there are C. 2000 people in society.
