ISSB Academic and Initial Tests flashcards — 50 questions with answers
What is the formula to express a number X as a percentage of a number Y?
(X / Y) × 100. For example, 30 as a percentage of 150 = (30/150) × 100 = 20%.
How do you calculate the percentage increase from an old value to a new value?
Percentage increase = ((New value − Old value) / Old value) × 100.
If a quantity is increased by 20% and then decreased by 20%, what is the net percentage change?
A net decrease of 4%. (Successive change = a + b + ab/100 = 20 − 20 + (20×−20)/100 = −4%.)
How do you find the original value when a final value and the percentage change are known (reverse percentage)?
Original = Final value ÷ (1 ± rate/100). For a 25% increase giving 250: Original = 250 ÷ 1.25 = 200.
What is the formula relating a ratio a:b to two actual quantities sharing a total T?
Each share = (ratio part / sum of ratio parts) × Total. For a:b sharing T, first = a/(a+b) × T, second = b/(a+b) × T.
In a proportion a:b = c:d, what is the key cross-multiplication rule?
The product of the means equals the product of the extremes: b × c = a × d.
What is the formula for the average (arithmetic mean) of a set of n numbers?
Average = (Sum of all values) / (Number of values) = Sum / n.
If the average of 5 numbers is 20 and one number is removed leaving an average of 18 for 4 numbers, what was the removed number?
28. (Total of 5 = 100; total of 4 = 72; removed = 100 − 72 = 28.)
What is the difference between direct proportion and inverse proportion?
In direct proportion, as one quantity increases the other increases at the same rate (x/y constant). In inverse proportion, as one increases the other decreases (x × y constant).
What is the formula for combined (weighted) average when two groups of sizes n1 and n2 have averages A1 and A2?
Combined average = (n1·A1 + n2·A2) / (n1 + n2).
What does the algebraic identity (a + b)² expand to?
(a + b)² = a² + 2ab + b².
What does the identity (a − b)² expand to?
(a − b)² = a² − 2ab + b².
What is the factorisation of a² − b² (difference of two squares)?
a² − b² = (a + b)(a − b).
What is the quadratic formula for solving ax² + bx + c = 0?
x = [−b ± √(b² − 4ac)] / (2a).
In a quadratic ax² + bx + c = 0, what does the discriminant b² − 4ac tell you?
If > 0, two distinct real roots; if = 0, one repeated real root; if < 0, no real roots (complex roots).
How do you solve a linear equation such as 3x + 5 = 20?
Isolate x: subtract 5 from both sides (3x = 15), then divide by 3 (x = 5).
What is the sum of the interior angles of a triangle, and of a quadrilateral?
A triangle's interior angles sum to 180°; a quadrilateral's interior angles sum to 360°.
State the Pythagorean theorem for a right-angled triangle.
In a right-angled triangle, the square of the hypotenuse equals the sum of the squares of the other two sides: c² = a² + b².
What are the formulas for the area and circumference of a circle of radius r?
Area = πr²; Circumference = 2πr (or πd, where d is the diameter).
What is the formula for the area of a triangle given base b and height h?
Area = ½ × base × height = ½ × b × h.

What are the formulas for the volume and total surface area of a cube of side a?
Volume = a³; Total surface area = 6a².
What is the formula for the volume of a cylinder with radius r and height h?
Volume = πr²h.
What is the formula for profit percentage in terms of cost price (CP) and selling price (SP)?
Profit% = ((SP − CP) / CP) × 100, where Profit = SP − CP.
How do you find the selling price when cost price and a desired profit percentage are known?
SP = CP × (1 + Profit%/100). For CP = 200 at 15% profit: SP = 200 × 1.15 = 230.
What is the formula for simple interest (SI)?
SI = (P × R × T) / 100, where P = principal, R = rate per annum, T = time in years.
What is the formula for compound interest amount (A)?
A = P(1 + R/100)^T; Compound Interest = A − P, where compounding is annual.
How is a discount percentage calculated, and on what value is it applied?
Discount% = (Discount / Marked Price) × 100. The discount is applied to the marked (list) price, not the cost price; Selling Price = Marked Price − Discount.
What are the three degrees of comparison for adjectives, with an example?
Positive, Comparative, and Superlative. Example: good, better, best (or tall, taller, tallest).
What is the difference between the simple present and the present continuous tense?
Simple present states habitual or general facts (She writes letters). Present continuous describes an action happening now (She is writing a letter).
What is the structure and use of the present perfect tense?
Structure: has/have + past participle (e.g., She has eaten). It links a past action to the present, often for completed actions with present relevance or unspecified time.
What are the three main types of conditional sentences and their typical tense patterns?
First conditional: If + present simple, will + base verb (real future). Second conditional: If + past simple, would + base verb (unreal present). Third conditional: If + past perfect, would have + past participle (unreal past).
What is the difference between active and passive voice, with an example?
In active voice the subject performs the action (The boy kicked the ball). In passive voice the subject receives the action (The ball was kicked by the boy); formed with be + past participle.
What is an idiom, and what does the idiom 'a piece of cake' mean?
An idiom is a phrase whose meaning differs from the literal meaning of its words. 'A piece of cake' means something very easy to do.

What does it mean to infer in a comprehension passage?
To infer is to draw a logical conclusion that is implied but not directly stated, using clues in the text combined with reasoning.
What is the basic rule of subject-verb agreement in sentence correction?
A singular subject takes a singular verb and a plural subject takes a plural verb (e.g., He runs / They run).
What common error does 'Neither of the boys are coming' contain, and what is the correction?
'Neither' is singular, so it needs a singular verb: 'Neither of the boys is coming.'
What is a misplaced modifier, and how is it corrected?
A misplaced modifier is a word or phrase positioned so it appears to describe the wrong thing. It is corrected by placing the modifier next to the word it actually describes (e.g., 'She almost drove the kids to school every day' → 'She drove the kids to school almost every day').
What is the difference between a synonym and an antonym?
A synonym is a word with the same or similar meaning (happy/joyful); an antonym is a word with the opposite meaning (happy/sad).
Give a synonym and an antonym for the word 'abundant'.
Synonym: plentiful (or ample). Antonym: scarce (or sparse).
