Answer 2

Given: During one month the bill for $25$ daily newspapers and $5$ Sunday newspapers was $Rs\ 155$ and During previous month bill was $Rs\ 159$ for $27$ dailies and $4$ Sundays.

To Find: What is the price of newspaper of Sunday.

Step-by-step explanation:

Lets,

      Dailies newspaper price is $Rs\ x$ and Sundays newspaper price is $Rs\ y$

In question given is,

During one month the bill for $25$ daily newspapers and $5$ Sunday newspapers was $Rs\ 155$.

So,

    $25x+5y=155$

⇒$5y=155-25x$

⇒$y=\frac{155}{5}-\frac{25}{5}x$

⇒$y=31-5x$__1

During previous month bill was $Rs\ 159$ for $27$ dailies and $4$ Sundays.

So,

    $27x+4y=159$

Plug the value of $y$ in above equation,

⇒$27x+4(31-5x)=159$

⇒$27x+124-20x=159$

⇒$7x=35$

⇒$x=\frac{35}{7}$

∴ $x=5$

Plug the value in equation-1,

⇒$y=31-(5\times 5)$

⇒$y=31-25$

∴ $y=6$

Therefore, The price of newspaper of Sunday is $Rs\ 6$.
