CFTRI M.Sc. (Food Technology) Mental Ability Flashcards
50 question-and-answer cards covering Mental Ability as it is examined in CFTRI M.Sc. (Food Technology). 24 of them are printed below, taken from across the deck — no signup, no paywall on the preview.
24 sample cards from the Mental Ability deck
Sampled from the end of the deck, so these are different cards from the ones shown on the syllabus page.
What is the formula to find percentage of a number?
Percentage value = (Percentage / 100) × Number. Example: 20% of 50 = (20/100) × 50 = 10.
How do you calculate percentage change?
Percentage change = [(New value − Old value) / Old value] × 100.
What is the formula for average?
Average = (Sum of all observations) / (Number of observations).
What is the formula for speed?
Speed = Distance / Time. Distance = Speed × Time; Time = Distance / Speed.
How do you convert km/hr to m/s?
Multiply by 5/18. Example: 36 km/hr × 5/18 = 10 m/s.
How do you convert m/s to km/hr?
Multiply by 18/5. Example: 10 m/s × 18/5 = 36 km/hr.
What is the formula for the ratio of two quantities?
Ratio = a : b = a/b; it compares two quantities of the same kind by division.
What is a proportion?
A statement that two ratios are equal, written a : b = c : d, where the product of means equals the product of extremes (b × c = a × d).
What is the LCM of two numbers?
The Least Common Multiple — the smallest positive number that is exactly divisible by both numbers.
What is the HCF (GCD) of two numbers?
The Highest Common Factor — the largest number that divides both numbers exactly.
What is the relationship between LCM, HCF and two numbers?
LCM × HCF = Product of the two numbers.
What is the formula for the area of a circle?
Area = π r², where r is the radius.
What is the formula for the perimeter (circumference) of a circle?
Circumference = 2 π r (or π d, where d is the diameter).
What is the area of a rectangle and a triangle?
Rectangle = length × breadth; Triangle = ½ × base × height.
What is the Pythagoras theorem?
In a right-angled triangle, the square of the hypotenuse equals the sum of squares of the other two sides: c² = a² + b².
What is a 'mirror image' in non-verbal reasoning?
The image of an object as seen in a mirror, where left and right are interchanged (lateral inversion) while top and bottom stay the same.
What is a 'water image' in non-verbal reasoning?
The reflection of an object in water, where top and bottom are interchanged (vertical inversion) while left and right stay the same.
What is the difference between deductive and inductive reasoning?
Deductive reasoning moves from general premises to a specific certain conclusion; inductive reasoning moves from specific observations to a probable general conclusion.
What is a Venn diagram used for in reasoning?
To represent logical relationships between groups/sets using overlapping circles, helping solve syllogisms and classification problems.
In a seating arrangement, what is the difference between a linear and a circular arrangement?
In linear, people sit in a row facing one direction; in circular, people sit around a table facing the center (or outside), and left/right depend on facing direction.
What is the formula for the number of diagonals in a polygon of n sides?
Number of diagonals = n(n − 3) / 2.
What is the sum of interior angles of a polygon with n sides?
Sum = (n − 2) × 180°.
In a 'cube and dice' problem, what is the rule for opposite faces of a standard die?
The numbers on opposite faces of a standard die always add up to 7 (1-6, 2-5, 3-4).
What is the difference between mean, median, and mode?
Mean is the average; median is the middle value when data is arranged in order; mode is the most frequently occurring value.
What this deck covers
The Mental Ability deck follows the CFTRI M.Sc. (Food Technology) Mental Ability syllabus — 14 chapters and 0 topics — so questions land on material that is genuinely examinable rather than trivia around it. That works out to roughly 3.6 cards per chapter.
Answers are written to be recallable, not just readable — averaging about 87 characters, which is long enough to carry the reasoning and short enough to say out loud.
A deck like this earns its keep on the second and third pass. Read the syllabus first so you know the shape of the subject, then use the cards to find the specific facts that have not stuck.
