In the following question, four groups of three numbers are given. In each group the second and third number are related to the first number by a Logic/Rule/Relation. Three are similar on basis of same Logic/Rule/Relation. Select the odd one out from the given alternatives.

If a Mirror is placed on the line MN, then which of the answer figure is the right image of the given figure ?

which of the following cube in the answer figure cannot be made based on the unfolded cube in the question figure ?

A word is represented by only one set of numbers as given in any one of the alternatives. The set of numbers given in the alternatives by represented by two classes of alphabets as shown in the  given two matrices. The columns and rows of matrix-1 are numbered from 0 to 4 and that of matrix-2 are numbered from 45 to 9. A letter from these matrices can be represented first  by its row and next by its column, for   example `D`can be represented by 12,34 etc and `R` can be represented by 95,97 etc. Similarly, you have to identify the set for the word `PLUS`.
