Answer 2

166.67%

Step-by-step explanation:

The computation of the percentage increase in grain production for the period 1950-1955 is shown below:

= (Year 1995 grain production - Year 1950 grain production) ÷ ( Year 1950 grain production)

= (1,600 million tons - 600 million tons) ÷ (600 million tons)

= 1,000 million tons ÷ 600 million tons

= 166.67%

Hence the increase in percentage is 166.67%
