Tips and Trciks to Solve Line chart Question 1 and 2

Question 1.

For which of the following pairs of years the total exports from the three Companies together are equal?

A. 1995 and 1998
B. 1996 and 1998
C. 1997 and 1998
D. 1995 and 1996

Answer: Option D
Explanation:
Total exports of the three Companies X, Y and Z together, during various years are:

In 1993 = (30 + 80 + 60) = 170

In 1994 = (60 + 40 + 90) = 190

In 1995 = (40 + 60 + 120) = 220

In 1996 = (70 + 60 + 90) = 220

In 1997 = (100 + 80 + 60) = 240

In 1998 = (50 + 100 + 80) = 230

In 1999 = (120 + 140 + 100) = 360

Clearly, the total exports of the three Companies X, Y and Z together are same during the years 1995 and 1996.

Question 2.

 What was the difference between the average exports of the three Companies in 1993 and the average exports in 1998?

A. 15.33
B. 18.67
C. 20
D. 22.1

Answer: Option C

Explanation:

Average exports of the three Companies X, Y and Z in 1993

= [ \frac{1}{3} \times (30 + 80 + 60)]

= \frac{170}{3}

Average exports of the three Companies X, Y and Z in 1998

= [\frac{1}{3} \times (50 + 100 + 80) ]= (\frac{230}{3})

Difference [(\frac{230}{3}) – (\frac {170}{3})]

= (\frac{60}{3})

= 20
