Question

36
15
10
24

Answer 1

36

Explanation:

This questions tests for the fundamentals of counting.

Let's say event
`x_i` can be done in X ways and event
`y_i` can be done in Y ways, therefore the total number of ways
`x_i` and
`y_i` can be done is given as
`xy`.

Applying this counting principle in our case, the total different sandwiches is obtained as the product of the individual sandwich types.

`Total=s* m* b\\=3* 4 * 3\\=36`

36 different sandwiches can be made.
