The total imports (in Billion) made by all the three companies together: From the heights of the points we observe that the total heights of three points is the maximum either in 1995 or 1997. If you observe carefully, our clear answer is 1995, but to be sure we find actual values for the two years.
In 1995 = 70 + 80 + 85 = 235.
In 1997 = 75 + 70 + 85 = 230.
Clearly, 1995 is the desired year.
