What this question type is
A mixed multiple-choice reasoning test — quantitative word problems, logical deductions, data interpretation, and applied "transfer" reasoning. Each question has one prompt and four options.
How to solve it
Read the category label; it hints at the skill. For quantitative items, set up the arithmetic step by step and beware of off-by-one traps. For logical items, apply the rule strictly — valid conclusions only follow from what's actually stated. For data/transfer items, identify the exact relationship being asked about (which model? proportional or inversely proportional?) before calculating.
Worked example
"If you have an apple, you cannot have a banana. You have a banana." By contrapositive, you therefore do not have an apple — that's the only conclusion that must be true.
Try it yourself
0 of 4 solvedWhy
Batch 1 = 6 ms, batch 2 = 6 + 3 = 9 ms, batch 3 = 9 + 3 = 12 ms. So 12 ms.
Why
The rule says apple → not banana. You have a banana, so by contrapositive you cannot have an apple. Grapes were never mentioned, so nothing follows about them.
Why
The question asks about Model A, which drops 15% per hour. Over 3 hours that's 45%. 100 − 45 = 55%. Model B's rate is a distraction.
Why
Inverse proportionality means doubling the thickness halves the rate: 60 ÷ 2 = 30 J/s.
