Answer:

The number of extra call of the month is [tex]1332\ Calls[/tex]

Step-by-step explanation:

Given charge of telephone up to [tex]175[/tex] calls is [tex]Rs\ 200[/tex]

And each additional call costs [tex]Rs\ 1[/tex]

Also, there are [tex]10[/tex] % TSC and  [tex]13[/tex] % VAT.

So, total tax is [tex]10+13[/tex] [tex]=23[/tex] %

And total bill paid is [tex]Rs\ 1988.8[/tex]

We need to find number of extra call of the month.

So, amount before paying the tax would be

[tex]1988.8[/tex] [tex]-14[/tex]% of [tex]1988.8[/tex]

[tex]=1988.8-1988.8\times\frac{14}{100}\\\\=1988.8-457.424\\\\=1531.376[/tex]

Also, minimum charge of telephone is [tex]Rs\ 200[/tex]

Amount after deduction minimum charge is

[tex]1531.376-200\\\\=Rs\ 1331.376[/tex]

It is given each additional call costs [tex]Rs\ 1[/tex]

So, total number of extra calls are [tex]\frac{Rs\ 1331.376}{Rs\ 1}=1331.376[/tex]≅[tex]1332\ Calls[/tex]
