Solution:
Option(B) is correct

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

1 - 3

15

1 - 3

20

1

25

3

30

2

We already know that the number of coins in 5 boxes that are colored Black are:
12, 15, 20, 25 and 30.

Given that the number of coins in the box that is colored Pink is 30.

Total number of boxes with Mr. Zero that are colored white is 2.

The total number of coins in the boxes that are colored White can be:

$(25 + 12 = 37)$,

$(25 + 15 = 40)$ and $(12 + 15 = 27)$

Hence, option (B) is the correct choice.

there is no possibility of number of coins being (12+15) i.e 27. since number of boxes having 25 coins is 3. and the pink box has 30 coins. so the box containing 25 coins must be the ones colored as black, white and yellow. so 25 must be included in the white boxes. so possible options are 40 and 37.
