14. A Keovan company received US Dollars 100,000. The money was converted into Kenyan shillings by a bank which buys and sells foreign currencies as follows:

\begin{tabular}{|c|c|c|}
\hline
Currency & Buying (Ksh) & Selling (Ksh) \\
\hline
US Dollar & 77.24 & 77.44 \\
\hline
\end{tabular}

(a) Calculate the amount of money in Kenyan shillings the company received.



Answer :

Let's solve the given problem step by step.

1. Identify the given information:
- The company received USD 100,000.
- The bank's buying rate for 1 USD is 77.24 Kenyan Shillings (Ksh).

2. Understanding the bank's buying rate:
- The buying rate is the rate at which the bank buys foreign currency from customers. In this context, it means the bank will exchange 1 USD for 77.24 Ksh.

3. Calculate the amount of money in Kenyan Shillings:
- We need to convert the received amount in USD to Ksh.
- To do this, we multiply the number of US Dollars by the buying rate.

[tex]\[ \text{Amount in Ksh} = \text{Amount in USD} \times \text{Buying Rate} \][/tex]

Plugging in the given values:

[tex]\[ \text{Amount in Ksh} = 100,000 \, \text{USD} \times 77.24 \, \text{Ksh per USD} \][/tex]

4. Perform the multiplication:
- When we multiply these values, we get:

[tex]\[ 100,000 \times 77.24 = 7,723,999.999999999 \, \text{Ksh} \][/tex]

Therefore, the amount of money the Keovan company received in Kenyan Shillings is 7,723,999.999999999 Ksh.
