You have learnt mathematical functions 2

Let us test if you have learnt some of those functions 3

Suppose you are running a lottery for your customers and you want to pick out a list of Five Lucky customers 4

So use the random function in your customer table and get me a list of 5 5

Randomly picked customers 6

Small hint 7

To do this you need to order your result 8

With the random values and limit it to 9

5 10

In your second activity 11

Suppose 12

You cannot charge the customer 13

In decimal points 14

So if you have a sales value of 1.63 15

You can either charge the customer one 16

Or two units 17

In this scenario 18

You have three options 19

Either to always take the lower integer value 20

So whenever you face 1.63 21

You'll always charge 1 22

or 23

You have the option of charging the higher integer value 24

Or 25

You'll round it off 26

Using the rounding off function 27

All these three will give you three different results 28

So find out the total sales revenue if you charge the lower integer value 29

The total sales revenue if you charge the higher integer value and the total sales revenue if you are rounding off 30

With these two simple activities we will be sure that 31

You have learnt the mathematical functions taught in the previous section and you are ready to move on to the next section
