Q1
Find the difference between the total number of cakes sold by bakery R and T together on January to that of total number of cakes sold by bakery P and S together on April?
The total number of cakes sold by bakery R and T together on January
[latex]\Rightarrow 250 + 360 = 610[/latex]
The total number of cakes sold by bakery P and S together on April
[latex]\Rightarrow 340 + 260 = 600[/latex]
Required difference = 610 – 600 = 10
Q2
Find the average number of cakes sold by bakery P on all the given months together?
The average number of cakes sold by bakery P on all the given months together
[latex]\Rightarrow \frac {(280 + 220 + 260 + 340)}{4}[/latex]
[latex]\Rightarrow \frac {1100}{4} = 275[/latex]
Q3
Find the ratio between the total number of cakes sold by bakery Q on January and March together to that of total number of cakes sold by bakery S on March and April together?
The total number of cakes sold by bakery Q on January and March together
[latex]\Rightarrow 320 + 330 = 650[/latex]
The total number of cakes sold by bakery S on March and April together
[latex]\Rightarrow 240 + 260 = 500[/latex]
Required ratio = 650 : 500 = 13 : 10
Q4
Total number of cakes sold by bakery P, Q and R together on February is approximately what percentage of total number of cakes sold by bakery R, S and T together on March?
Total number of cakes sold by bakery P, Q and R together on February
[latex]\Rightarrow 220 + 270 + 210 = 700[/latex]
Total number of cakes sold by bakery R, S and T together on March
[latex]\Rightarrow 340 + 240 + 250 = 830[/latex]
Required % = [latex](\frac {700}{830}) \times 100 = 84.33 % = 84 %[/latex]
Q5
If the total number of cakes sold by bakery P on May is 20 % more than the average number of cakes sold by bakery P on all the given months together, find the total number of cakes sold by bakery P on May?
The total number of cakes sold by bakery P on May
[latex]\Rightarrow [\frac {(280 + 220 + 260 + 340)}{4}] \times (\frac {120}{100})[/latex]
[latex]\Rightarrow (\frac {1100}{4}) \times (\frac {6}{5})[/latex]
[latex]\Rightarrow 330[/latex]
