#The problem is on greeting telegram and ordinary telegram CHARGES.If there are 13 words so how can i apply the rate of charges

To calculate the cost of the telegram with 13 words, you need to consider the base cost of 10 words and the additional cost for the remaining 3 words.

Let's break it down step by step:

1. Calculate the base cost for 10 words:
The ordinary telegram costs Sh 3 for 10 words, so the cost will be Sh 3.

2. Calculate the additional cost for the remaining 3 words:
Each extra word has a charge of 30 cents. As there are 3 extra words, the additional cost will be 3 * 30 cents, which is 90 cents in total.

3. Add the base cost and the additional cost to find the total cost:
The base cost is Sh 3 and the additional cost is 90 cents (or 0.90 Sh). Therefore, the total cost will be Sh 3 + 0.90 Sh, which is Sh 3.90.

So, the cost of the telegram with 13 words will be Sh 3.90.
