Question

The bar graph above shows the number of tons of beans produced on a large farm for the years $1985$ through $1991$. For which of the following two-year periods was the average (arithmetic mean) bean production closest to the bean production in $1985$ ?

• A. $1986-1987$
• B. $1987-1988$
• C. $1988-1989$
• D. $1989-1990$
• E. $1990-1991$

Answer 1

The correct option is A $1986-1987$

In given bar graph the production in year $1985$ is $18$.

And production in $1986$ is $20$ and production in year $1987$ is $16$.

Then mean of production in year $1986-1987$ $=$ $\frac{20+16}{2}=18$

Then(A) in $1986-1987$ period is average production closest to production in $1985$.
