24) What is the ratio of the total sales of branch B2 for both the years to the total sales of the branch B4 for both the years
- 1) 4:9
- 2) 4:11
- 3) 7:9

View Answer
View Explanation
Ans. C
Explanation :
\begin{aligned}
\text{Required Ratio = }\frac{75+65}{85+95} \= \frac{140}{180} \= \frac{7}{9} = 7:9
\end{aligned}
25) What percent of the average sales of branches B1, B2 and B3 in 2001 is the average sales of the branches B1, B3 and B6 in 2000
- 1) 83.5%
- 2) 87.5%
- 3) 88.5%
- 4) 89.5%

View Explanation
Ans. B
Explanation :
Average sales (in thousand numbers) of branches B1, B3 and B6 in 2000 are
\begin{aligned}
=\frac{1}{3}*(80+95+70) \= \frac{245}{3} \\end{aligned}
Average sales (in thousand numbers) of branches B1, B2 and B3 in 2001 are
\begin{aligned}
=\frac{1}{3}*(105+65+100) \= \frac{280}{3} \
\text{Required Percentage =}\left( \frac{\frac{245}{3}}{\frac{280}{3}}*100 \right)\% \= \left( \frac{245}{280}*100 \right) \% \= 87.5 \%
\end{aligned}
26) Total sales of branch B6 for both the years is what percent of the total sales of the branch B3 for both the years
- 1) 73.17%
- 2) 72.17%
- 3) 71.17%
- 4) 70.17%

View Explanation
Ans. A
Explanation :
Required Percentage =
\begin{aligned}
\left[\frac{(70+80)}{(95+110)}*100 \right]\% \= \frac{150}{205}*100 \% \= 73.17 \%
\end{aligned}
