ICET Logical Reasoning 2 — Questions and Answers
Question 1: Five friends P, Q, R, S, T sit in a row. Q is at the leftmost position. P sits immediately to the right of Q. T sits between P and S. R sits to the left of S. Who sits in the middle (3rd position)?
- P
- R
- T (Correct answer)
- S
Correct answer: T
Placing Q first, P second, then T between P and S, and R left of S gives the order Q, P, T, R, S, placing T in the middle.
Question 2: In a class, Ravi is 7th from the top and 28th from the bottom. How many students are in the class?
- 33
- 34 (Correct answer)
- 35
- 36
Correct answer: 34
Total students = position from top + position from bottom − 1 = 7 + 28 − 1 = 34.
Question 3: All flowers are beautiful. Rose is a flower. Which conclusion definitely follows?
- All beautiful things are flowers
- Rose is beautiful (Correct answer)
- Some flowers are not roses
- Beautiful things are roses
Correct answer: Rose is beautiful
Since all flowers are beautiful and Rose is a flower, it logically follows that Rose must be beautiful.
Question 4: 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 3×30° + 15×0.5° = 97.5°, giving a difference of 7.5°.
Question 5: If '+' means '×', '−' means '÷', '×' means '−', and '÷' means '+', what is the value of 8 + 4 − 2 × 3 ÷ 1?
- 13
- 14 (Correct answer)
- 12
- 15
Correct answer: 14
Substituting operators gives 8 × 4 ÷ 2 − 3 + 1; applying order of operations: 32 ÷ 2 − 3 + 1 = 16 − 3 + 1 = 14.
Question 6: Complete the series: 1, 4, 9, 16, 25, ?
- 30
- 36 (Correct answer)
- 42
- 49
Correct answer: 36
The sequence is perfect squares (1², 2², 3², 4², 5²), so the next term is 6² = 36.
Question 7: Statement: The production cost of solar panels has dropped by 80% over the last decade. Which assumption is implicit in this statement?
- Solar energy is now cheaper than coal
- Solar panels were very expensive a decade ago (Correct answer)
- Manufacturing technology has improved
- Government subsidies reduced prices
Correct answer: Solar panels were very expensive a decade ago
An 80% drop implies that the original cost was significant; the statement implicitly assumes solar panels were expensive before the decline.
