Answer 1

Answer :

Roy earns 34% on sales of pizza and 12% on sales on coke .

And ,

This week he earned Rs 55.88. His sales of pizza were Rs 2 more than his sales of coke.

Let sale of pizza = x

So sale of coke = x - 2

And from given information , we get

34% of x + 12% of ( x -2 ) = 55.88

$$\begin{gathered} \Rightarrow \frac{34x}{100}+\frac{12}{100}\left(x-2\right)=55.88 \\ \Rightarrow \frac{34x}{100}+\frac{12}{100}x-\frac{24}{100}=55.88 \\ TakingLCMweget \\ \Rightarrow \frac{34x+12x-24}{100}=55.88 \end{gathered}$$

46x - 24 = 5588

46x = 5612

x = 122

So,

He earn by selling Pizza = $\frac{34\times 122}{100}=\frac{4148}{100}$ = Rs. 41.48 ( Ans )
