Question

The minimum charge of the first 100 calls of telephone is Rs 250 and additional calls are 189. If the total charge is Rs 769.75, what is the rate of additional call?

Answer 1

Step-by-step explanation:

The minimum charge up to 100 calls is Rs 250.if charge for each additional call Is Rs 1.50. How much will be the charge for 420 calls with 10% TSC and 13% VAT.

Soln

Charge for 100 calls = Rs. 250

Now, additional calls = 420 – 100 = 320

So, cost of 320 calls = 320 * Rs. 1.50 = Rs. 480.

So, the total cost = Rs. 250 + Rs. 480 = Rs. 730

Now, Cost with 10% TSC = Rs. 730 + 10% of Rs. 730

= 730 + 10100 * 730

= Rs. 803.

Now, Cost with 13% VAT = Rs. 803 + 13% of 803

= Rs. 803 + 104.39

= Rs. 907.39
