Show answer & explanation
Correct answer: B
Ans. B.
By the given table,
Sales of Suzuki in year 2005 = 8800
Sales in year 2006 due to 5% increase = 8800 + 440 = 9240
Average sales of Suzuki in year 2001 and 2006 = (8500+9240)/2 = 8870
Sales of Yamaha in year 2005 = 7000
In 2006, due to decrease of 5% sales= 7000 – 350 = 6650
Sales of Yamaha in year 2002 = 6400
Average of sales in 2002 and 2006 of Yamaha = (6400+6650)/2 = 6525
Now difference of average sales of Suzuki and Yamaha
= 8870 – 6525 = 2345
