Total farmers = 1000
Paddy = 600
Ragi = 350
Corn = 280
Paddy and Ragi = 120
Ragi and Corn = 100
Paddy and Corn = 80
Paddy only = 600 - 120 - 80 = 400
Ragi only = 350 - 120 - 100 = 130
Corn only = 280 - 100 - 80 = 100
Find the farmers that grew all three
Farmers that grew all three = 1000 - 120 - 100 - 80 - 400 - 130 - 100 = 70
Answer: 70 farmers grew all three
