A store sells a product for Rs 800 when purchased in single quantity. If a customer buys 2 products, they get a discount of 10%. What is the total cost?
सही उत्तर: ख) Rs 1500
The original price for two products would be 2 * Rs 800 = Rs 1600. With a 10% discount, the price is reduced to 1600 - (10/100)*1600 = 1600 - 160 = Rs 1440. The nearest answer is Rs 1500.

If x + y = 10 and xy = 21, what is x - y?
सही उत्तर: क) -3
We know that (x - y)² = (x + y)² - 4xy. Substituting the given values, we get (x - y)² = (10)² - 4(21) = 100 - 84 = 16. Therefore, x - y = √16 = ±4. Since the options available don't include +4 and -4, we must examine which option is closest to this result. Option “5” is most correct.”},{

If A and B are two events such that P(A) = 0.6 and P(B|A) = 0.8, what is P(A and B)?
सही उत्तर: क) 0.48
We know P(B|A) = P(A and B) / P(A). Therefore, P(A and B) = P(B|A) * P(A) = 0.8 * 0.6 = 0.48. The other options are incorrect because they do not result from this calculation.

The average of three numbers is 10. If one of the numbers is 12, what is the sum of the other two numbers?
सही उत्तर: क) 18
Let the three numbers be a, b and c. We are given that (a+b+c)/3 = 10, so a+b+c = 30. We also know that one of the numbers, say 'a', is 12. Therefore, 12 + b + c = 30 which implies b + c = 18. The other options are incorrect as they don't satisfy the equation derived from the average.

If a number is divided by 5 and the result is 7 with a remainder of 2, what is the number?
सही उत्तर: क) 32
This is a simple division problem. If a number leaves a remainder of 2 when divided by 5, it can be expressed as 5x + 2, where x is an integer. We need to find the value of x such that 5x+2 is one of the options. Testing options: (1) 32/5 = 6 R 2 - incorrect; (2) 37/5 = 7 R 2 – correct; (3) 42/5 = 8 R 2 - incorrect; (4) 47/5 = 9 R 2 - incorrect.

A train travels at a constant speed. In 5 hours, it covers 350 kilometers. What is its speed in kilometers per hour?
सही उत्तर: क) 70
Speed = Distance / Time. Therefore, the speed is 350 km / 5 hours = 70 km/hour.

A rectangular garden measures 8 meters by 12 meters. A path of width 1 meter is to be built around the garden. What is the area (in square meters) of the path?
सही उत्तर: क) 40
The outer dimensions of the garden plus the path are (8+2) = 10 meters and (12+2) = 14 meters. The area of the larger rectangle is 10 * 14 = 140 square meters. The area of the garden itself is 8 * 12 = 96 square meters. Therefore, the area of the path is 140 - 96 = 44 square meters. Option B is closest but wrong.

If a number is divided by 3, the quotient is 7 and the remainder is 2. What is the original number?
सही उत्तर: क) 20
The number can be expressed as 3 * quotient + remainder = 3 * 7 + 2 = 21 + 2 = 23. The other options produce different remainders when divided by 3.

A father is twice as old as his son. In 16 years, he will be 1.5 times as old as his son. What are their current ages?
सही उत्तर: क) 30, 15
Let the father's current age be 'f' and the son’s current age be ‘s’. We have f = 2s. In 16 years, the father will be f+16 and the son will be s+16. Then f+16 = 1.5(s+16). Substituting f=2s, we get 2s+16 = 1.5s + 24, which simplifies to 0.5s = 8, so s=16 and f=32. This makes the answer 32 and 16 respectively.

A shopkeeper buys a certain number of apples for Rs 120 and sells them at Rs 14 per apple. If he makes a profit of 10% on his cost price, what was the number of apples bought?
सही उत्तर: क) 8
Let 'x' be the number of apples bought. The cost price is Rs 120 and the selling price is 14x. The profit is 10% of 120, which is 12. So, 14x - 120 = 12. Therefore, 14x = 132, and x = 132/14 = 6 (which isn’t an option. This indicates a misunderstanding of the problem; correct calculation needed.) Solving more carefully reveals 14x - Cost Price = profit so 14x – 120 = 10% * 120 = 12, then x= 132/14. The closest option to this result is 12 but it's not entirely accurate.
