Question 1: If TRAIN is coded as USBJM, how is RAIL coded?
- SBJM (Correct answer)
- TBKM
- SBLM
- RBKM
Correct answer: SBJM
Each letter is shifted one position forward: R→S, A→B, I→J, L→M = SBJM.
Question 2: Find the odd one out: 8, 27, 64, 100, 125
- 8
- 27
- 100 (Correct answer)
- 125
Correct answer: 100
100 is the odd one out because 8=2³, 27=3³, 64=4³, 125=5³ are perfect cubes, but 100 is not.
Question 3: If the day before yesterday was Thursday, what day will be the day after tomorrow?
- Sunday

If day before yesterday = Thursday, today = Saturday, day after tomorrow = Monday.
Question 4: Pointing to a man, a woman says, 'His mother is the only daughter of my mother.' How is the woman related to the man?

The only daughter of the woman's mother is the woman herself, so she is the man's mother.

The differences are 4, 6, 8, 10, 12, so the next number is 30 + 12 = 42.
