The minimum charge of telephone call up to 175 calls is Rs 200 and the charge of each
additional call is Rs 2. If a man paid Rs 1104 with 13% VAT of his one month telephone bill.
find how many extra calls of that month was made.
​

Answer 1

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.
