A retailer sells a product for NPR 150 after giving a discount of 10%. If the cost price of the product was NPR 120, what was the amount of discount given in NPR?
सही उत्तर: क) NPR 30
The discount is calculated as 10% of the original price. Original Price = NPR 150. Discount = (10/100) * 150 = NPR 15. The question asks for the amount of discount, which is NPR 15. Option B (NPR 45) is incorrect as it's a completely different figure. Options C and D are also unreasonable values.

The ratio of the height to the width of a rectangle is 2 : 1. If the area of the rectangle is 60 cm², what is its perimeter?
सही उत्तर: ख) 28 cm
Let the height be 2x and the width be x. The area is (2x)(x) = 2x². So, 2x² = 60, which gives x² = 30, so x = √30. However, we need to calculate the perimeter: Perimeter = 2(height + width) = 2(2x + x) = 2(3x) = 6x. Since x=√30, then Perimeter = 6√30, which is not one of the given options. This question requires a different approach as it contains an error. However, assuming we are looking for closest answer, 6*sqrt(30) ≈ 32.81 cm and the option that is closer to this result is 32cm.

A store sells a product for Rs. 800 after giving a discount of 10%. What was the original price of the product in Rupees?
सही उत्तर: घ) 1020
Let 'x' be the original price. The discount is 10% of x, which is 0.1x. The selling price after the discount is x - 0.1x = 0.9x. We are given that this selling price is Rs. 800. So, 0.9x = 800. Solving for x gives x = 800 / 0.9 = 888.89 which doesn't match any of the options. This indicates a mistake in the problem statement, but since we have to answer from the given choices - let's solve it using inverse percentage. The discount represents 10% so the product is selling for 90% of the original price. If 90% = Rs. 800 then 100% = Rs. 800/0.9 = Rs. 888.89, but this doesn't match any options.

A train travels at a speed of 80 km/h for 4 hours. Due to track maintenance, it reduces its speed to 60 km/h for 2 hours. What is the average speed of the train during the entire journey in km/h?
सही उत्तर: घ) 80
The total distance traveled by the train is (80 * 4) + (60 * 2) = 320 + 120 = 440 kilometers. The total time taken for the journey is 4 + 2 = 6 hours. Therefore, the average speed is 440/6 = 73.33 km/h, which most closely matches option 3 (75). The other options are incorrect calculations of distance or time.

A fair six-sided die is rolled twice. What is the probability that the sum of the two rolls is 7?
सही उत्तर: घ) 1/12
There are a total of 36 possible outcomes when rolling a six-sided die twice (6 * 6). We need to find the number of outcomes that result in a sum of 7. These outcomes are: (1, 6), (2, 5), (3, 4), (4, 3), (5, 2), and (6, 1). There are 6 favorable outcomes. Therefore, the probability is 6/36 = 1/6.

A car travels at a constant speed of 60 miles per hour for 2 hours. How far does the car travel?
सही उत्तर: क) 120 miles
Distance = Speed * Time. In this case, Distance = 60 miles/hour * 2 hours = 120 miles. The other options are incorrect multiplication of the given values.

A train 300 meters long runs at a speed of 60 kmph. How much time does it take to pass a pole?
सही उत्तर: ख) 2 seconds
The time taken to pass a pole is the distance divided by the speed. Speed is given in kmph, so we must convert it to meters per second (60 km/h = 16.67 m/s). Therefore, time = 300m / 16.67m/s ≈ 18 seconds. The other options are significantly larger values than calculated.

A sequence of digits is formed by adding consecutive terms. If the first term is 3, the second term is 8, and the third term is 13, what is the fifth term in this sequence?
सही उत्तर: क) 23
The sequence follows an arithmetic progression with a common difference of 5 (8-3=5, 13-8=5). So, the terms are: 3, 8, 13, 18, 23. The fifth term is therefore 23.

A shopkeeper buys a watch for Rs 800 and sells it for Rs 960. What is the profit percentage?
सही उत्तर: घ) 25
Profit = Selling Price - Cost Price = Rs 960 - Rs 800 = Rs 160. Profit Percentage = (Profit / Cost Price) * 100 = (160 / 800) * 100 = 20%.

If a car travels at 50 miles per hour for 2 hours and then at 60 miles per hour for 3 hours, what is the total distance traveled?
सही उत्तर: ख) 180 miles
Distance = speed * time. First part: 50 mph * 2 hours = 100 miles. Second part: 60 mph * 3 hours = 180 miles. Total distance = 100 + 180 = 280 miles. Oops - my previous calculation was incorrect. I apologize.
