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.

A coin is tossed 4 times. What is the probability of getting at least one tail?
सही उत्तर: घ) 15/16
P(no tails) = (1/2)^4 = 1/16, so P(at least one tail) = 1 − 1/16 = 15/16. 1/16 is the complement itself.

A card is drawn from a standard 52-card deck. What is the probability that it is a king or a heart?
सही उत्तर: ग) 4/13
P(king) + P(heart) − P(king of hearts) = 4/52 + 13/52 − 1/52 = 16/52 = 4/13. 17/52 double-counts the king of hearts.

A bag has 4 red and 6 blue balls. Two balls are drawn without replacement. What is the probability that both are red?
सही उत्तर: ख) 2/15
(4/10) × (3/9) = 12/90 = 2/15. 4/25 = (4/10)² assumes replacement.
