  • a)
    8
  • b)
    3
  • c)
    11
  • d)
    17
Correct answer is option 'B'. Can you explain this answer?

Iq Funda answered
We have to minimize the number of dealers who sold Wagon R.
So to minimize the number of dealers, the dealers who have largest share in total sales should have maximum share of Wagon R.
So if we assume that Q and R sold Wagon R the maximum number of Wagon R’s they can sell is 25% of 51 which is equal to 12.75%.
But the overall share of Wagon R is 16% so there should be at least 1 more dealer who sells Wagon R.
Hence the correct answer is 3.
