2. An average tube bath uses 8 gallons of water and an average shower uses 6 gallons to provide baths for 60 men. How much more water will be needed if tubs are used instead of showers?

Correct Answer: Correct answer is: (B) 120 gallons.

Exam Relevance: GMAT, GRE, SAT, ACT

Difficulty: Moderate

Concept notes: The question requires comparing the water usage for showers versus baths for 60 men and determining the additional water needed if baths are used instead of showers.

Common Mistakes: A common mistake is to misinterpret the question and calculate the total water usage for either showers or baths without comparing the difference.

Explanations: To determine the additional water needed if tubs are used instead of showers, we need to calculate the difference in water usage between the two options for 60 men. 1. Calculate the total water usage for showers: - Each shower uses 6 gallons. - For 60 men, the total water usage for showers is \( 60 \times 6 = 360 \) gallons. 2. Calculate the total water usage for baths: - Each bath uses 8 gallons. - For 60 men, the total water usage for baths is \( 60 \times 8 = 480 \) gallons. 3. Determine the additional water needed if tubs are used instead of showers: - The difference in water usage is \( 480 - 360 = 120 \) gallons. Thus, 120 gallons more water will be needed if tubs are used instead of showers.

Option Analysis:

Option A: 30 gallons is incorrect because it does not reflect the difference in water usage between showers and baths for 60 men.
Option B: 120 gallons is correct as it accurately represents the additional water needed if tubs are used instead of showers.
Option C: 360 gallons is incorrect because it represents the total water usage for showers, not the additional water needed.
Option D: 480 gallons is incorrect because it represents the total water usage for baths, not the additional water needed.

3. Elephant is 1,2 ton. Hippo is 1500 kg. Giraffe is 550 kg. Tiger is 0,75 ton. The lightest animal based on the data is .....

Correct Answer: Correct answer is: (C) Giraffe.

Exam Relevance: SAT, ACT, GRE, GMAT

Difficulty: Easy

Concept notes: The question requires comparing the weights of different animals to determine the lightest one.

Common Mistakes: A common mistake could be misinterpreting the units of measurement (ton vs. kg) or not converting all weights to the same unit before comparison.

Explanations: To determine the lightest animal, we need to compare their weights. First, convert all weights to the same unit, such as kilograms (kg): - Elephant: 1.2 tons = 1,200 kg - Hippo: 1,500 kg - Giraffe: 550 kg - Tiger: 0.75 tons = 750 kg Comparing these weights: - Elephant: 1,200 kg - Hippo: 1,500 kg - Giraffe: 550 kg - Tiger: 750 kg The lightest animal is the Giraffe, weighing 550 kg.

Option Analysis:

Option A: Elephant weighs 1,200 kg, which is not the lightest.
Option B: Hippo weighs 1,500 kg, which is not the lightest.
Option C: Giraffe weighs 550 kg, which is the lightest.
Option D: Tiger weighs 750 kg, which is not the lightest.

Correct Answer: Correct answer is: B) Paper B.

Exam Relevance: SAT, GRE, GMAT, CAT

Difficulty: Easy

Concept notes: To compare performance in two different papers, we need to calculate the percentage scores for each paper and then compare them.

Common Mistakes: A common mistake is to compare the raw scores directly without converting them to percentages, which can lead to incorrect conclusions.

Explanations: To determine in which paper Ram performed better, we need to calculate the percentage scores for both papers. For Paper A: - Raw score: 18 - Total possible score: 70 - Percentage score: \(\frac{18}{70} \times 100 = 25.71\%\) For Paper B: - Raw score: 14 - Total possible score: 30 - Percentage score: \(\frac{14}{30} \times 100 = 46.67\%\) Comparing the percentage scores, Ram's performance in Paper B (46.67%) is better than in Paper A (25.71%). Therefore, the correct answer is B) Paper B.

Option Analysis:

Option A: Incorrect because the percentage score in Paper A is lower than in Paper B.
Option B: Correct because the percentage score in Paper B is higher than in Paper A.
