A. 10 B. 25 C. 40 D. 55

A
The total number of cakes sold by bakery R and T together on January
$\Rightarrow 250 + 360 = 610$
The total number of cakes sold by bakery P and S together on April
$\Rightarrow 340 + 260 = 600$
Required difference = 610 – 600 = 10

$\Rightarrow \frac {1100}{4} = 275$

Q3

A. 17 : 12 B. 13 : 10 C. 25 : 19 D. 34 : 27

B
The total number of cakes sold by bakery Q on January and March together

Total number of cakes sold by bakery R, S and T together on March
$\Rightarrow 340 + 240 + 250 = 830$
Required % = $(\frac {700}{830}) \times 100 = 84.33 % = 84 %$

Q5

A. 330 B. 350 C. 320 D. 360

A
The total number of cakes sold by bakery P on May
$\Rightarrow [\frac {(280 + 220 + 260 + 340)}{4}] \times (\frac {120}{100})$
$\Rightarrow (\frac {1100}{4}) \times (\frac {6}{5})$
$\Rightarrow 330$
