Question

Refer to the following table which gives changes in market shares of five brands over a five year period.

	1998	1999	2000	2001	2002
A	33	32	28	31	35
B	6	8	9	11	13
C	27	29	32	28	22
D	19	19	18	20	21
E	15	12	13	10	9

Rules :
a. If market share increases for $3$ years in a row, the brand is called a 'strengthening' brand.
b. If market share remains above $30\%$ for $3$ years out of a total of $5$ years, then it is a 'consistent' brand.
c. If market share is failing for $3$ years in a row, the brand is called a 'weakening' brand.
d. If market share drops for $2$ years in a row and then rises for $2$ years in a row, it is a 'relaunched' brand.
e. If market share varies by $3$ points or less over the past year for $5$ years in a row then it is a 'maverick' brand.
f. If in any year, $80\%$ of, total market share is accounted for three brands, then that year is a 'year of competition'.
g. If any year, just two brands account for at least $60\%$ of total market share, then that year is a 'consolidation year.'
Note : For 'weakening brands', fall for $3$ years would mean the date should show a declining trend for $3$ years from a base year.
What was average market share of brands A and B from $1998to2002$?

• A. $41.2$
• B. $206$
• C. $51.5$
• D. $65$
• E. $34.3$

Answer 1

The correct option is A $41.2$

Average market share of A and B from $1998-2002$ = $\frac{SumofmarketshareAandBfrom1998-2002}{5}$
= $\frac{(33+6)+(32+8)(28+9)(31+11)(35+13)}{5}$ =$\frac{206}{5}$ = $41.2$ Hence, [a]
