By comparing the Sale of Pep-up for all years and we found that the Sale of Pep-up was the maximum in the year 1989.
Difference in Required number = Number of Pep-up drink sold in 1990 - Number of Cool-sip drink sold in 1990.
Difference in Required number = 30 million ? 20 million = 10 million.
Difference in Required number = 10 million = 10 x 1000000 ( Since 1 million = 1000000 )
Difference in Required number = 10 million = 10000000
As per given graph we can see the difference is very less in 1998. Obvious from the chart its 1998 .
Obvious from the chart , we can say that 1998?1999 year has the same import and export.
As we can see in the graph that metropolises location has continuous increase both in appeared and passed.
Our intelligent observation says that the required year cannot be 1993, 1994, 1995. Why? Because see the following conclusions:
% passed to appear = Passed / Appeared x 100
% of passed to appear is least when Passed / Appeared is the least or, Appeared / Passed is the most.
Now, we do the further calculations mentally. See the following conclusions:
For 1990: 7894 / 2513 ? Quotient = 3 and Remainder ? 300
For 1991: 8562 / 2933 ? Q = 3 and R ? 400
For 1992: 8139 / 2468 ? Q = 3 and R ? 800
Similarly, for 1993; 1994, 1995, Q is 2.
So, 1992 gives the highest value.
