Imagine there is only one cookie jar left in the universe and you found it in a room. Sadly, it is closed and can be opened only with a 3- number combination in specific order. Along the cookie jar you found 3 other items , suspected to be clues for the combination:
Item 1:
Hand clock showing time 03:00:10
Item 2:
A circular disc with 7 sectors each having different number, colour and picture:
1- Indigo - Wafer
2- Brown - Pizza slice
3- Pink - Chocolate
5- Yellow - Cotton Candy
6- Orange - Liquor
7- Blue - Toffee
8- Green - Chips
$$\begin{array}{c|c|c|} \text{Number} & \text{Colour} & \text{Picture} \\ \hline \text{1} & \text{Indigo} & \text{Wafer} \\ \hline \text{2} & \text{Brown} & \text{Pizza Slice} \\ \hline \text{4} & \text{Pink} & \text{Chocolate} \\ \hline \text{5} & \text{Yellow} & \text{Cotton Candy} \\ \hline \text{6} & \text{Orange} & \text{Liquor} \\ \hline \text{7} & \text{Blue} & \text{Toffee} \\ \hline \text{7} & \text{Green} & \text{Chips} \\ \hline \end{array}$$
Item 3:
3 balloons with strips in line
Yellow balloon with blue strip
Red balloon with blue strip
Yellow balloon with red strips
Also the Wall of the room bears an inscription:
use $2/3$2/3 and get
_ + _ + _ =16_ + _ + _ =16
Find the combination to open the jar.
Adding a hint :
Walls says use 2/3 means 2 items out of 3 and one item is just for distraction.
_ + _ + _=16_ + _ + _=16 tells that sum of three numbers of the combination is 16. Rest is up to you.
