There are 4 blue ribbons, 5 silver ribbons and 3 yellow ribbons.

Step-by-step explanation:

We need to find the smallest number of rolls of each type :

For this we will find "L.C.M of 15,12 and 20".

L.C.M of 15,12 and 20 = 60

So, Number of rolls of blue ribbon is given by

Number of rolls of silver ribbon is given by

Number of rolls of yellow ribbon is given by

Hence, there are 4 blue ribbons, 5 silver ribbons and 3 yellow ribbons.
