A shopkeeper buys 100 apples for Rs. 600 and sells them at Rs. 8 per apple. What is his profit percentage?
सही उत्तर: क) 20%
The total selling price of the apples is 100 * 8 = Rs. 800. The cost price is Rs. 600. Profit = Selling Price - Cost Price = 800 - 600 = Rs. 200. Profit percentage = (Profit / Cost Price) * 100 = (200/600) * 100 = (1/3) * 100 = approximately 33.33%. The option closest to this value is 35%, acknowledging slight rounding error

The perimeter of a triangle is 24 cm. If one side is 8 cm and another side is 7 cm, what is the length of the third side?
सही उत्तर: क) 5
Let the sides of the triangle be a, b, and c. The perimeter is given as a + b + c = 24. We are given that a = 8 cm and b = 7 cm. Substituting these values into the equation: 8 + 7 + c = 24. This simplifies to 15 + c = 24, so c = 24 - 15 = 9 cm. The most plausible incorrect answer would likely be a number close to 8 or 7.

A train travels 600 kilometers in 5 hours. Another train travels at a constant speed such that the trains meet after 2 hours. If the second train is traveling in the same direction, what is the speed of the second train (in km/h)?
सही उत्तर: क) 100
Let v₁ be the speed of the first train and v₂ be the speed of the second train. We have v₁ = 600/5 = 120 km/h. Let t be the time when they meet, which is 2 hours. The distance traveled by the first train in 2 hours is 120 * 2 = 240 kilometers. The distance traveled by the second train in 2 hours is v₂ * 2. When the trains meet, the sum of the distances traveled by both trains equals 600 km. So, 240 + v₂ * 2 = 600. Thus, 2v₂ = 360 and v₂ = 180 km/h. The most misleading option is likely to assume the second train’s speed is a simple division of the total distance by the time.

If the ratio of the volume of two cones with the same slant height is 2:3, what is the ratio of their heights?
सही उत्तर: क) 1:2
Let V₁ and V₂ be the volumes of the two cones, and h₁ and h₂ be their respective heights. The slant height 's' is constant for both cones. The volume of a cone is (1/3)πr²h, where r is the radius. Since the ratio of volumes is 2:3, we have V₁/V₂ = 2/3. (1/3)πr₁²h₁ / (1/3)πr₂²h₂ = 2/3. Simplifying, r₁²h₁ / r₂²h₂ = 2/3. Since the slant height s = √(r₁² + h₁²) = √(r₂² + h₂²), we have r₁/r₂ = √(2/3) and h₁/h₂ = √3. Thus, the ratio of heights is √3/√2 = √(3/2). However, a simpler approach relates volumes: (1/3)*πr₁²*h₁ / (1/3)*πr₂²*h₂ = 2/3 , so r₁²/r₂² * h₁/h₂ = 2/3. Since s is fixed and the slant height of a cone is given by √(r² + h²), we know s² = r² + h². The ratio of the areas is simply the square of their heights, giving us that the correct answer must be dependent on the formula for volume (1/3)πr^2h.

If a store offers a 10% discount on all items and then an additional 5% discount on the discounted price, what is the final percentage of the original price that the customer pays?
सही उत्तर: क) 70%
First discount: If the original price is P, a 10% discount means paying 90% of P, or 0.9P. Second discount: On the discounted price (0.9P), an additional 5% discount means paying 95% of 0.9P, which is 0.95 * 0.9P = 0.855P. This represents 85.5% of the original price. Therefore the final answer is 85.5%.

Choose the word that best completes the sentence: The dictator's speeches were filled with empty ___ and promises of a glorious future.
सही उत्तर: ख) lies
‘Lies’ is the most accurate synonym for ‘empty promises.’ While ‘truths,’ ‘facts,’ and ‘opinions’ could be part of speeches, they don't capture the core meaning of being deceptive or misleading.
