Sales of Books (in thousand numbers) from Six Branches - B1, B2, B3, B4, B5 and B6 of a publishing Company in 2000 and 2001.

3.
What percent of the average sales of branches B1, B2 and B3 in 2001 is the average sales of branches B1, B3 and B6 in 2000?
75%
77.5%
82.5%
87.5%
Answer: Option
Explanation:

Average sales (in thousand number) of branches B1, B3 and B6 in 2000

    = 1 x (80 + 95 + 70) = ( 245 ) .
3 3

Average sales (in thousand number) of branches B1, B2 and B3 in 2001

    = 1 x (105 + 65 + 110) = ( 280 ) .
3 3

Therefore Required percentage = [ 245/3 x 100 ] % = ( 245 x 100 ) % = 87.5%.
280/3 280

What happened 3 in both the cases?
Anomie said:   6 years ago
Both 3 got nullify with each other like 245÷3 /280÷3 = 245÷3 * 3÷280 = hence 245÷280 * 100, we get 87.5%.

B1, B2, B3 in 2001 should be numerators and B1, B3, B6 in 2000 should be denominator.
