The number of boxes that are colored Pink, Yellow, White and Black is 1, 2, 2 and 5 respectively.
It is also given that no two boxes that are colored with the same color have equal number of coins.
It is also given that the number of coins in each of the ten boxes is 12, 15, 20, 25 or 30.
Also, since there are five boxes that are colored, the number of coins in the boxes are 12, 15, 20, 25 and 30.
| Number of Coins | Number of Boxes |
12 | 01-Mar |
| 15 | 01-Mar |
| 20 | 1 |
| 25 | 3 |
| 30 | 2 |
Given that the total number of coins in the boxes that are colored Yellow is maximum possible, which means that, the total number of coins in the boxes that are colored Yellow is:25+30=55
Also, since the total number of coins in all the boxes is least,which means that the number of boxes in which there are 15 coins and 12 coins is 1 and 3 respectively.
So, the only possibility that is left is the box that is colored Pink has 12 coins and the two boxes that are colored White have 25 and 12 coins
