A book cost 3 Euro. If the rate of exchange is 1 euro = 8naira:33 kobo find the cost in naira

To find the cost of the book in naira, we need to convert 3 euros into naira using the given exchange rate.

1 euro = 8 naira
0.33 kobo = 1 euro

First, we convert 0.33 kobo to euros:
0.33 kobo = 0.33/100 euros = 0.0033 euros

Then, we add this to the 3 euros:
3 euros + 0.0033 euros = 3.0033 euros

Now, we can convert euros to naira:
1 euro = 8 naira
3.0033 euros = 3.0033 * 8 naira = 24.0264 naira

So, the cost of the book in naira is approximately 24.03 naira.
