The bar graph given below shows the sales of books (in thousand number) from six branches of a publishing company during two consecutive years 2000 and 2001.

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%
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

 Required percentage = 245/3 x 100 % = 245 x 100 % = 87.5%. 280/3 280

Agree with you @Nikita Gupta.

2001's value should be placed as the numerator and the other as the denominator...
So, the correct answer is 114.24%.

Here, the answer should be 84% because in 2001 it is asked to calculate the average of b1, b3 and b6.

It's b6 not b2.

I think the correct answer has to be 89.2%.

But we have to divide the sum of observations by the number of observations which gives 93. 3 & 81.66.

After all, it gives answers wrong.

Why we have take 245 as numinrator rather than taking denominator?

B6 = 80.

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

Both 3 got nullify with each other like 245÷3 /280÷3 = 245÷3 * 3÷280 = hence 245÷280 * 100, we get 87.5%.
