Some alphabets are given below. First arrange them in alphabetical order from left to right then number them I, II, III, IV, V from left to right.
1) J, P, D, B, S
2) C, M, A, Q, X
3) W, I, T, N, O
Arrange all separately in each number. Which of the following is in alphabetical order?
- A.
Only I and III
- B.
Only II and IV
- C.
Only II and III
- D.
Only III and IV
- E.
Only II, III and IV
Show answer & explanation
Correct answer: D
CONCEPT:
In this column-comparison task, each numbered set is first sorted into alphabetical order. The five sorted positions are then labelled I, II, III, IV and V from left to right. Reading a single position down across all the sets gives a column; a position is "in alphabetical order" only if the letters in that column ascend from the top set to the bottom set.
APPLICATION:
Sort each set alphabetically: Set 1 becomes B, D, J, P, S; Set 2 becomes A, C, M, Q, X; Set 3 becomes I, N, O, T, W.
Stack the three sorted sets and read each of the five positions top-to-bottom to form columns I to V.
Test each column for an ascending (alphabetical) sequence down its three letters.
Sorted grid (read each column downward):
Position | I | II | III | IV | V |
|---|---|---|---|---|---|
Set 1 | B | D | J | P | S |
Set 2 | A | C | M | Q | X |
Set 3 | I | N | O | T | W |
Checking each column downward:
Column I: B, A, I — A comes before B, so it breaks ascending order.
Column II: D, C, N — C comes before D, so it breaks ascending order.
Column III: J, M, O — J < M < O, a clean ascending run.
Column IV: P, Q, T — P < Q < T, a clean ascending run.
Column V: S, X, W — W comes before X, so it breaks ascending order.
CROSS-CHECK: Exactly two columns ascend without a single inversion — the position holding J, M, O and the position holding P, Q, T. Re-reading those two columns confirms every letter is later in the alphabet than the one above it, while the other three columns each contain at least one out-of-place pair.
Result: The positions III and IV are the two that read in alphabetical order.
