Question 1 of 20Ratios
The ratio of boys to girls in a class is 3:5. If there are 64 students, how many are boys?
Explanation: The total ratio is 8 parts. Boys represent 3 parts, so 64 × 3/8 = 24 boys.
Question 2 of 20Weighted Averages
Twenty students have an average score of 60, while thirty students have an average of 70. What is the combined average?
Explanation: The total score is 20 × 60 + 30 × 70 = 3,300. Dividing by 50 gives 66.
Question 3 of 20Cyclic Patterns
What is the units digit of 7²³?
Explanation: The units digits repeat 7, 9, 3, 1. Since 23 mod 4 = 3, the units digit is 3.
Question 4 of 20Profit and Loss
An item costs Rs. 800 and is sold for Rs. 920. What is the profit percentage?
Explanation: Profit is 920 − 800 = 120. Profit percentage is 120/800 × 100 = 15%.
Question 5 of 20Algebraic Identities
If x + 1/x = 5, what is x² + 1/x²?
Explanation: Squaring gives x² + 2 + 1/x² = 25. Therefore, x² + 1/x² = 23.
Question 6 of 20Successive Percentages
A product receives successive discounts of 20% and 10%. What is the single equivalent discount?
Explanation: The remaining price is 0.80 × 0.90 = 72% of the original, so the equivalent discount is 28%.
Question 7 of 20Speed, Distance and Time
A car travels 150 km in 3 hours at a constant speed. What is its speed?
Explanation: Speed equals distance divided by time. Therefore, 150 ÷ 3 = 50 km/h.
Question 8 of 20Sets and Venn Diagrams
In a group of 100 people, 60 know English, 45 know Urdu, and 25 know both. How many know neither language?
Explanation: Using inclusion-exclusion, 60 + 45 − 25 = 80 know at least one. Therefore, 100 − 80 = 20 know neither.
Question 9 of 20Direct Variation
If y varies directly as x and y = 18 when x = 6, what is y when x = 10?
Explanation: For direct variation, y/x is constant. Since 18/6 = 3, y = 3 × 10 = 30.
Question 10 of 20Coordinate Geometry
What is the distance between the points (2, 3) and (8, 11)?
Explanation: Distance = √[(8 − 2)² + (11 − 3)²] = √(36 + 64) = 10.
Question 11 of 20Inequalities
What is the smallest integer satisfying 2x − 5 > 9?
Explanation: Solving gives 2x > 14, so x > 7. The smallest integer solution is 8.
Question 12 of 20Basic Probability
A bag contains 3 red balls and 2 blue balls. What is the probability of drawing a red ball?
Explanation: There are 5 balls in total and 3 are red. The probability is therefore 3/5.
Question 13 of 20Area of Triangles
What is the area of a triangle with base 14 cm and height 9 cm?
Explanation: Triangle area is 1/2 × base × height. Therefore, 1/2 × 14 × 9 = 63 cm².
Question 14 of 20Clock Problems
What is the smaller angle between the hands of a clock at 3:40?
Explanation: The hour hand is at 110° and the minute hand at 240°. Their smaller difference is 130°.
Question 15 of 20Arithmetic Sequences
What is the 10th term of the arithmetic sequence 5, 9, 13, 17, ...?
Explanation: The common difference is 4. The 10th term is 5 + 9 × 4 = 41.
Question 16 of 20Boats and Streams
A boat travels at 18 km/h downstream and 10 km/h upstream. What is the speed of the stream?
Explanation: Stream speed equals half the difference: (18 − 10) / 2 = 4 km/h.
Question 17 of 20Quadratic Equations
What is the larger root of x² − 7x + 12 = 0?
Explanation: Factor as (x − 3)(x − 4) = 0. The roots are 3 and 4, so the larger root is 4.
Question 18 of 20Discounts
A shirt marked Rs. 1,500 is offered at a 20% discount. What is the sale price?
Explanation: The discount is 20% of 1,500 = 300. Subtracting gives 1,500 − 300 = Rs. 1,200.
Question 19 of 20Compound Interest
What is the compound interest on Rs. 10,000 at 10% annually for 2 years?
Explanation: The amount is 10,000(1.10)² = 12,100. Compound interest is Rs. 2,100.
Question 20 of 20Pipes and Cisterns
Pipe A fills a tank in 6 hours, pipe B in 8 hours, and a drain empties it in 24 hours. How long will all three take together?
Explanation: The net rate is 1/6 + 1/8 − 1/24 = 1/4 tank per hour. The tank fills in 4 hours.
