Directions (1-5): Imports of 3 companies over the year (Rs. in crore)
Q1. In which of the following years, the imports made by Company A was exactly equal to average imports made by it over the given years?
(d) None of these
Q2. In which of the following years was the difference between the imports made by Company B and C the maximum?
Sol. By visual inspection it is clear that 1992 is the desired
year (as the distance between two points is the maximum in 1992).
Q3. In which of the following years was the imports made by Company A exactly half of the total imports made by Company B and C together in that years?
(a) 1992 only
(b) 1993 only
(c) 1992 and 1993
(d) 1995 only
Q4. What was the percentage increase in imports of Company B from 1992 to 1993?
Q5. In which of the following years was the total imports made by all the three companies together is the maximum?
(a) 1996 only
(b) 1997 only
(c) 1995 only
(d) 1995 and 1997 only
Sol. The total imports (in Crore) made by all the three companies
together: From the heights of the points we observe 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.
