Mettl Problem-Solving & Logical Reasoning 4 — Questions and Answers
Question 1: Arrange the steps to solve a problem logically: (1) Evaluate solutions, (2) Define the problem, (3) Implement the best solution, (4) Generate possible solutions.
- 2, 4, 1, 3 (Correct answer)
- 1, 2, 3, 4
- 4, 2, 1, 3
- 2, 1, 4, 3
Correct answer: 2, 4, 1, 3
The logical order is: define the problem, generate solutions, evaluate them, then implement the best one.
Question 2: A rectangle's length is twice its width. If the perimeter is 60 cm, what is the area?
- 150 cm²
- 200 cm² (Correct answer)
- 100 cm²
- 300 cm²
Correct answer: 200 cm²
Width = 10, length = 20; perimeter = 2(10+20) = 60; area = 10 × 20 = 200 cm².
Question 3: Odd one out: January, March, June, August, October
- January
- March
- June (Correct answer)

Correct answer: June
June has 30 days; all other months listed have 31 days.
