​

Answer 1

Answer:

Step-by-step explanation:

Given charge of telephone up to 175 calls is

Rs 200

And each additional call costs Rs 1

Also, there are 10 % TSC and 13 % VAT.

So, total tax is 10+13=23%

And total bill paid is Rs 1988.8

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

So, amount before paying the tax would be

1998.8 -14% of 1988.8

- 1988.8 - 1988.8 x 14/100

=1988.8 - 457.424

=1531.376.

Also, minimum charge of telephone is Rs 200

Amount after deduction minimum charge is 1531.376-200

Rs 1331.376

It is given each additional call costs Rs 1

So, total number of extra calls are Rs

1331.376/Rs 1=1331.376=1332 calls.

I hope this helps

you.
