GRE Quantitative Comparison. Quantity A: the area of a circle with radius 2. Quantity B: the area of a square with side 3.5. Which is true?
सही उत्तर: ख) Quantity A is greater
Circle: 4π ≈ 12.57; square: 3.5² = 12.25. So Quantity A is slightly greater.

GRE Quantitative Comparison. Quantity A: √50 + √2. Quantity B: √72. Which is true?
सही उत्तर: क) The two quantities are equal
√50 + √2 = 5√2 + √2 = 6√2, and √72 = 6√2. They are equal.

GRE Quantitative Comparison. Quantity A: the average of 1/2 and 1/3. Quantity B: 2/5. Which is true?
सही उत्तर: घ) Quantity A is greater
(1/2 + 1/3)/2 = (5/6)/2 = 5/12 ≈ 0.417, which is greater than 2/5 = 0.4.

GRE Quantitative Comparison. Quantity A: (−3)⁴. Quantity B: −3⁴. Which is true?
सही उत्तर: ग) Quantity A is greater
(−3)⁴ = 81, while −3⁴ means −(3⁴) = −81. The exponent applies before the negative sign unless parentheses enclose the −3.

GRE Quantitative Comparison. Quantity A: 0.5% of 400. Quantity B: 2. Which is true?
सही उत्तर: ख) The two quantities are equal
0.5% of 400 = 0.005 × 400 = 2, so the quantities are equal. Reading 0.5% as 0.5 (giving 200) is the usual trap.

GRE Quantitative Comparison. Quantity A: the number of minutes in a week. Quantity B: 10,000. Which is true?
सही उत्तर: क) Quantity A is greater
Minutes in a week = 60 × 24 × 7 = 10,080, which exceeds 10,000.

GRE Quantitative Comparison. x > 0. Quantity A: x². Quantity B: x³. Which is true?
सही उत्तर: घ) The relationship cannot be determined
If x = 2, B is larger (4 vs 8); if x = 1/2, A is larger (1/4 vs 1/8); if x = 1 they are equal. Since different allowed values give different results, the relationship cannot be determined.

If every value in a data set is increased by 5, what happens to the standard deviation?
सही उत्तर: ग) It stays the same
Adding a constant shifts all values equally, so the spread (and the standard deviation) is unchanged; the mean increases by 5. Multiplying each value by 5 would multiply the SD by 5.

What is the median of the data set 7, 3, 9, 1, 5, 11?
सही उत्तर: ख) 6
Sorted: 1, 3, 5, 7, 9, 11. With an even count, the median is the average of the middle two: (5 + 7)/2 = 6.

How many 3-digit numbers can be formed from the digits 1–5 if no digit may be repeated?
सही उत्तर: क) 60
5 × 4 × 3 = 60. 125 = 5³ allows repeated digits, and 10 = C(5,3) ignores order.
