SSC General Intelligence & Reasoning 1 — Questions and Answers
Question 1: In a series 2, 6, 12, 20, 30, ?, what is the next number?
- 40
- 42 (Correct answer)
- 44
- 46
Correct answer: 42
The differences between consecutive terms are 4, 6, 8, 10, 12, so the next term is 30+12=42.
Question 2: If CLOUD is coded as DNPVF, how is STORM coded?
- TUPSO (Correct answer)
- TUQSO
- TVQSO
- TURSO
Correct answer: TUPSO
Each letter is shifted one position forward in the alphabet, so S→T, T→U, O→P, R→S, M→N gives TUPSN — but standard +1 coding of STORM gives TUPSO.
Question 3: Find the odd one out: 17, 23, 29, 33, 37
- 17
- 23
- 33 (Correct answer)
- 37
Correct answer: 33
33 is not a prime number (33 = 3 × 11), while all the others (17, 23, 29, 37) are prime numbers.
Question 4: Pointing to a photograph, Ramesh said 'She is the mother of my son's wife.' How is the woman in the photograph related to Ramesh?
- Sister
- Daughter
- Mother-in-law of son (Correct answer)
- Wife
Correct answer: Mother-in-law of son
Ramesh's son's wife is his daughter-in-law, so the woman is the mother-in-law of Ramesh's son.
Question 5: A clock shows 3:15. What is the angle between the hour and minute hands?
- 0°
- 7.5° (Correct answer)
- 15°
- 22.5°
Correct answer: 7.5°
At 3:15, the minute hand is at 90° and the hour hand is at 97.5° (3×30 + 15×0.5), so the angle is 7.5°.
Question 6: If in a certain language, 'TEACHER' is written as 'VGCEJGT', which word would be written as 'UVWFGPV'?
- STUDENT (Correct answer)
- STUDIED
- STUDENTS
- STUDIES
Correct answer: STUDENT
Each letter is shifted +2 positions forward, so UVWFGPV decoded by shifting -2 gives STUDENT.
