In the IELTS scoring system, what does ‘Task Achievement’ primarily assess?
सही उत्तर: क) Overall fluency and coherence
The answer is 0 (‘The extent to which the task requirements have been fully addressed’). This accurately describes what ‘Task Achievement’ measures - how well the candidate fulfills the specific instructions and criteria of the writing task. Options 1, 2 and 3 represent other aspects of the overall IELTS band scores.

In a class of 60 students, 35 are male and the remaining are female. If 15 of the males play cricket, how many male students do not play cricket?
सही उत्तर: क) 20
Total number of students = 60. Number of male students = 35. Number of female students = 60 - 35 = 25. Students who play cricket = 15 (male). Therefore, the number of male students who do not play cricket is 35 – 15 = 20.

If all squares are rectangles and some rectangles are not parallelograms, which statement must be true?
सही उत्तर: ख) Some rectangles are not parallelograms
The question uses a syllogistic reasoning approach. The fact that some rectangles are *not* parallelograms means there exist rectangles which do not fulfill the properties of a parallelogram. Since all squares are rectangles, it means there is an intersection between the set of rectangles and the set of parallelograms. The other options don't logically follow from the given premises.

A student is forming a 4-digit PIN code using digits from 0 to 9, with no repetition allowed. How many different PIN codes can be formed?
सही उत्तर: क) 24
This is a permutation problem. There are 10 digits (0-9). The first digit cannot be 0, so we have 9 choices for the first digit. Then there are 9 remaining choices for the second digit, 8 for the third, and 7 for the fourth. So, 9 * 9 * 8 * 7 = 4536. The closest answer among those provided is 900, indicating a misunderstanding of the calculation.

The median of the data set {6, 12, 9, 15, 7, 11} is:
सही उत्तर: ख) 12
First, arrange the data in ascending order: {6, 7, 9, 11, 12, 15}. The median is the middle value when the data is sorted. In this case, it’s 9. The other options are either values from the dataset or are not representative of the central tendency.

A merchant buys a certain number of apples for Rs 60 and sells them at Rs 7 per apple. If he makes a profit of 10% on the cost price, how many apples did he buy?
सही उत्तर: ग) 60
Let 'x' be the number of apples bought. The cost price is Rs 60 and the selling price is 7x. Profit = Selling Price - Cost Price. Given profit is 10% of 60, which is 6. So, 7x - 60 = 6 , thus 7x = 66 and x=9.2857, but this option is not available. The correct calculation is (selling price- cost price)/cost price *100 = 10. Hence (7x-60)/60*100=10. Solving for x gives x=60/7 which is approx 8.57, which is not available . The question means to state that he sells the apples at Rs 7 per apple and makes a profit of 10% on the cost price. So 7x = 60 + (10% of 60). 7x = 60+6=66; thus x=66/7 approx 9.4285, again not an option. I think there is a mistake in the question.

The area of a right-angled triangle is 30 cm² and one of its acute angles is 30°. What is the length of the hypotenuse?
सही उत्तर: क) 6√3
In a right-angled triangle with a 30° angle, the other acute angle is 60°. This means we have a 30-60-90 triangle. The sides are in the ratio 1:√3:2. Let the shorter side (opposite to the 30° angle) be 'a'. Then, the area = (1/2) * a² = 30, so a² = 60 and a = √60 = 2√15. The hypotenuse is 2a = 4√15. However, there seems to be an error in our calculation. Let’s reconsider the problem: Area = (1/2) * base * height = 30 cm². Let the base = x and height = y. Since it's a right-angled triangle with one angle being 30°, we have tan(30°) = y/x = 1/√3, so y = x/√3. The area is (1/2) * x * (x/√3) = 30 => x² / (2√3) = 30 => x² = 60√3 => x = √(60√3). This approach isn’t working easily with the given options. We can use sine and cosine properties related to the 30-60-90 triangle: sin(30°) = 1/2, cos(30°) = √3/2. Let one of the sides be 'a', the hypotenuse be 'h'. Then a / h = sin(30°) = 1/2 => a = h/2. Also (1/2) * a * b = 30. Using pythagoras theorem: a² + b² = h². The first equation says that a=h/2. Substituting, we get (h/2)² + b² = h², so h²/4 + b² = h² => b² = h²/4 => b = h/2. Therefore, area = (1/2) * (h/2) * (h/2) = h²/8 = 30 => h² = 240 => h = √(240) = √(16*15) = 4√15. The correct answer is 4√15 and by approximation, it’s close to 15.
