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?
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 |
 Required percentage = |

245/3 | x 100 | ![]](/_files/images/data-interpretation/common/15-sym-cbracket-h1.gif) |
% = | |
245 | x 100 | |
% = 87.5%. |

In the question the part which asks "what percentage of", should always be considered as the denominator substitution.
Ie. What percent of part: average sales of B1, B2, B3.
Numberator: Average sales of B1, B3, B6 = 245/3 = 81. 67.
Denominator:Average sales of B1, B2, B3 = 280/3 = 93. 33.
So, numerator/denominator = (81. 67/93. 33) *100% = 0. 88*100%= 87. 5%.
Answer is D.

Basically, the question asks for b1,b2,b3 in 2001: b1, b3, b6 in 2000 if we divide then 280/245 * 100= 114.28 % and the solution is given for the opposite one is 245/280 * 100 = 87.5%.

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%.

Can any one tell me the short cut to solve these kind of problems, where big numbers are involved in division like the one above, 245/280= 0.875.

Question is Avg of 2001 % of Avg 2000 %. The answer however is other way round.
avg of 2001 (93.3) of avg of 2000 ( 81.6)
which would be 113.97
avg of 2001 (93.3) of avg of 2000 ( 81.6)
which would be 113.97

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.

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

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.
It's b6 not b2.
