LUNG - UNLG - GNUL
FERN - ERFN - NREF
The question asks to identify the triad that follows the same logical transformation pattern as the given examples: LUNG - UNLG - GNUL and FERN - ERFN - NREF.
By analyzing the letter transformations in the provided examples, two distinct rearrangement rules are identified:
The letters of the first word are rearranged according to the positions 2, 3, 1, 4 to form the second word.
| Original Position | 1 | 2 | 3 | 4 |
|---|---|---|---|---|
| New Position Sequence | 2 3 1 4 | |||
Example: LUNG -> U N L G
The letters of the second word are rearranged according to the positions 4, 2, 1, 3 to form the third word.
| Original Position | 1 | 2 | 3 | 4 |
|---|---|---|---|---|
| New Position Sequence | 4 2 1 3 | |||
Example: UNLG -> G N U L
We will now check each option against these two transformation rules:
This option perfectly follows the established logic.
Only Option 1 adheres to both transformation rules derived from the examples.
Select the number from among the given options that will come next in the following series.
$20, 40, 63, 90, 122,$ _____
Select the option figure in which the given figure (X) is embedded (rotation is NOT allowed).

Identify the figure given in the options which when put in place of ? will logically complete the series.

When is a series of terms said to be in the order of increasing extension?
(A) When each term in the series (except the first) denotes a class having more members than a class denoted by the term preceding it.
(B) When the class size gets larger with each successive term.
(C) When each term in the series (except the first) denotes a class having fewer members than the class denoted by the term preceding it.
(D) When the class size gets smaller with each successive term
