A circular table has a diameter of 14 cm. What is its area (use π = 22/7)?
सही उत्तर: क) 65π sq.cm
The radius of the table is half the diameter, so r = 7 cm. The area of a circle is given by πr². Substituting the values gives Area = (22/7) * 7² = (22/7) * 49 = 22 * 7 = 154 square centimeters.

If the product of two numbers is 49 and one number is -7, what is the other number?
सही उत्तर: क) 7
Let the two numbers be 'x' and 'y'. Their product is x * y = 49. We are given that one of the numbers is -7. So (-7) * y = 49. Dividing both sides by -7 gives y = -7.

A man has 3 red shirts and 2 blue shirts. He wants to buy more shirts such that the ratio of red shirts to blue shirts is 2:1. How many blue shirts must he buy?
सही उत्तर: क) 1
Let 'x' be the number of blue shirts he needs to buy. After buying 'x' blue shirts, he will have 3 red shirts and x+1 blue shirts. The ratio of red to blue is 2:1, so 3 / (x+1) = 2/1. Cross-multiplying gives 3 = 2(x+1), or 3 = 2x + 2. Solving for x gives 2x = 1, so x = 0.5. Since he must buy a whole number of shirts, this question contains an error.

A ladder 5 meters long leans against a wall. The foot of the ladder is 3 meters away from the base of the wall. What is the height at which the ladder reaches on the wall?
सही उत्तर: क) 2.5 meters
This problem can be solved using the Pythagorean theorem: a² + b² = c², where 'a' and 'b' are the sides of the right triangle (wall and ground) and 'c' is the hypotenuse (ladder). In this case, 3² + b² = 5². So, 9 + b² = 25. Therefore, b² = 16, and b = 4. The height at which the ladder reaches on the wall is 4 meters.

Quantity A: The product of two numbers is 36. One number is 9. What is Quantity A?
सही उत्तर: क) 4
Given that the product of two numbers is 36 and one number is 9, let the other number be 'x'. So, 9 * x = 36. Dividing both sides by 9 gives x = 4. Therefore, Quantity A is 4.

If a train travels at a speed of 60 km/h and another train travels at a speed of 80 km/h in opposite directions, their relative speed is?
सही उत्तर: क) 140km/h
When two objects move towards each other, their speeds are added to find the relative speed. 60 km/h + 80 km/h = 140 km/h. The other options result from incorrect addition or misunderstanding of relative velocity.

Choose the sentence that correctly utilizes an infinitive phrase:

Which of these sentences demonstrates correct subject-verb agreement?
सही उत्तर: ख) The team is playing well
Option 1 is correct. In British English, ‘team’ (a collective noun) can be treated as singular, therefore ‘is’ agrees with the subject. Option 2 incorrectly uses a plural verb form for a singular subject. Options 3 and 4 both misuse the verb 'are' with ‘teams’.

Select the sentence with the most accurate usage of conditional mood:
सही उत्तर: ख) If I had known, I wouldn't have acted that way
Option 1 is correct. This sentence utilizes the third conditional structure accurately – describing a past unreal situation and its hypothetical consequence. Options 2 and 3 use incorrect tense pairings within the conditional clause. Option 4 incorrectly uses the present simple.
