SSC General Intelligence & Reasoning

Question 1

In a series 2, 6, 12, 20, 30, ?, what is the next number?

Accepted Answer

42

Answer

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?

Accepted Answer

TUPSO

Answer

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

Accepted Answer

33

Answer

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?

Accepted Answer

Mother-in-law of son

Answer

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?

Accepted Answer

7.5°

Answer

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°.
