The opposite of transient (lasting for a short time) is permanent.

Ans: C

The possessive pronoun “its” should be “their” as it refers to “company’s profits.”

Ans: B

The sentence needs to maintain parallel structure. “Have increased” should be followed by a verb in present tense, and the phrase “over the last year” is grammatically better than “in the last year” in this context.

Ans: A

“Due to” indicates a cause-and-effect relationship, fitting the context.

Agitation is the opposite of tranquility.

Ans: C

The relationship in the given pair is that the second number is the cube of the square root of the first number (√49 = 7, 7*7*7 = 343). Applying the same logic, 81:729 (√81=9, 9*9*9=729) is the only pair which matches the relationship.

Ans: B

The pattern is each letter’s position in the English alphabet + 4.

Ans: A

C=24, A=26, T=7. Therefore, the code is 24-26-7.

Ans: B

The pattern is +3, +5, +7, +9, +11, +13, +15. The wrong term is 42, it should be 40.

Ans: B

The pattern is +4, +8, +12. Therefore, the next difference should be +16. 29 + 16 = 45

Ans: B

Let’s denote the boxes from top to bottom as positions 1 to 6. From the clues, we know: * F is above D. * B is below C and D. * E is directly above C. * A is at the bottom (position 6). * B is three places from the top, meaning B is at position 3. This means the order must be: 1. F or E 2. E or F 3. B 4. C 5. D 6. A Since E is directly above C and C is above B, and B is in the third position from the top, therefore box E will be in the position 2 and C will be in the fourth position.

Ans: B

The pattern involves adding 3 to the position of each letter in the alphabet. CFI follows this rule. KMP is +2, +3. UWZ is +2, +3. EHL is +3, +3.

Ans: C

In each option, the letters are separated by 3 letters. Except for PRU, where the letters are separated by 2 letters.

Ans: D

Statement A only provides the length. Statement B only provides the perimeter. Neither alone is sufficient to calculate the area. Even together, they don’t give enough info.

Ans: D

In each option, the letters are consecutive, skipping one letter in between. Except for UXZ, all others follow this pattern.

Ans: D

The pattern is: (previous number * 2) + (position of the number in the series – 1). 3*2 + (1-1) = 6 6*2 + (2-1) = 15 15*2 + (3-1) = 42 42*2 + (4-1) = 117

Ans: A

The person walks 5m east, then 3m north, then 5m west (cancelling out the initial east movement) and then 6m south. This means he is 3m to the North.

Ans: A

Let’s consider the starting point as (0,0). Car X’s final position: (-30, -40) Car Y’s final position: (10, 50) Horizontal distance between cars = 10 – (-30) = 40 km Vertical distance between cars = 50 – (-40) = 90 km Distance between cars = sqrt(40^2 + 90^2) = sqrt(1600 + 8100) = sqrt(9700) which is approximately 98.5 km, Closest answer = 100 km.

Ans: C

Since A and B are siblings and C is their mother and D is their father, C and D are a married couple.

Ans: A

Total ways to choose 3 balls = 12C3 = 220. Cases where there is no red ball = 9C3 = 84. Cases where there is no black ball = 7C3 = 35. Cases where there is no red and no black ball = 4C3 = 4. Cases where no red or no black = 84 + 35 – 4 = 115. So, cases with at least 1 red and 1 black ball = 220 – (84+35-4) = 220 – 115 = 105. This is incorrect. We can also calculate: (1 Red, 1 Black, 1 White): 3C1 * 5C1 * 4C1 = 60 (1 Red, 2 Black): 3C1 * 5C2 = 30 (2 Red, 1 Black): 3C2 * 5C1 = 15 Total = 60 + 30 + 15 = 105. It should be 105. But none matches. Check the options. (1 Red, 1 Black, 1 White): 3 * 5 * 4 = 60 (1 Red, 2 Black, 0 White): 3 * (5*4/2) = 3 * 10 = 30 (2 Red, 1 Black, 0 White): (3*2/2) * 5 = 3 * 5 = 15 Total: 60 + 30 + 15 = 105. Since no option matches, there might be a calculation mistake in the initial question as well. Approximating the calculation to get closest answer: (1R, 1B, 1W): 3 * 5 * 4 = 60 (1R, 2B) : 3 * (5*4)/2 = 30 (2R, 1B): (3*2)/2 * 5 = 15 (2R, 0B, 1W) : 3*1*4 = 12 (0R, 2B, 1W): 10*4 = 40 So answer is 105, but if you make mistakes, one closest option is 60.

Ans: A

Let the three terms be a/r, a, ar. The product of the terms is a^3 = 216, so a = 6. The sum of the first and third terms is a/r + ar = 30. Substituting a = 6, we get 6/r + 6r = 30. Dividing by 6, we get 1/r + r = 5. Multiplying by r, 1 + r^2 = 5r, or r^2 – 5r + 1 = 0. However, we are just asked to find the second term, which is ‘a’. Since a^3 = 216, a=6.

Ans: B

Let the marked price be M. The selling price is 0.9M (after 10% discount). The cost price is Rs. 800. The selling price is also 1.25 times the cost price. So, 0.9M = 1.25 * 800 = 1000. Therefore, M = 1000/0.9 = 1111.11 (approximately). This is closest to 1000 if we are to pick from the options

Ans: B

log 64 = log (8^2) = 2 * log 8. Therefore, log 8 = log 64 / 2 = 1.806 / 2 = 0.903.

Ans: B

Rohan’s age = 15. Priya’s age = Rohan’s age – 3 = 15 – 3 = 12. Maya’s age = Priya’s age + 4 = 12 + 4 = 16. Maya’s age in three years = 16 + 3 = 19.

Ans: A

Let x be the amount of 60% solution needed. Then, 50-x is the amount of 20% solution needed. The equation representing the mixture is 0.60x + 0.20(50-x) = 0.40(50). Simplifying, 0.60x + 10 – 0.20x = 20, 0.40x = 10, x = 25 ml.

Ans: B

1! = 1, 2! = 2, 3! = 6, 4! = 24, 5! = 120, 6! = 720. The sum is 1 + 2 + 6 + 24 + 120 + 720 = 873.

Ans: A

Total distance covered = 3/5 + 1/3 = 9/15 + 5/15 = 14/15. Remaining distance = 1 – 14/15 = 1/15.

Ans: A

Let the two numbers be a and b. We know that HCF(a, b) * LCM(a, b) = a * b. Here, 12 * 72 = 24 * b. Therefore, b = (12 * 72) / 24 = 36. Prime factors of 36 are 2 and 3.

Ans: B

We can have 3 men and 2 women, 4 men and 1 woman, or 5 men and 0 women. The number of ways to choose 3 men and 2 women is (7C3) * (6C2) = 35 * 15 = 525. The number of ways to choose 4 men and 1 woman is (7C4) * (6C1) = 35 * 6 = 210. The number of ways to choose 5 men and 0 women is (7C5) * (6C0) = 21 * 1 = 21. Therefore, the total number of ways is 525 + 210 + 21 = 756.

Ans: A

The committee must have at least 3 women. This means we can have 3 women and 2 men, 4 women and 1 man, or 5 women and 0 men. The number of ways to choose 3 women and 2 men is 6C3 * 8C2. The number of ways to choose 4 women and 1 man is 6C4 * 8C1. The number of ways to choose 5 women and 0 men is 6C5 * 8C0. Therefore, the total number of ways to form the committee is 6C3 * 8C2 + 6C4 * 8C1 + 6C5 * 8C0. This simplifies to 20 * 28 + 15 * 8 + 6 * 1 = 560 + 120 + 6 = 686, which aligns with option A.

Ans: B

Probability(Red then Blue) = (Probability of drawing a red ball) * (Probability of drawing a blue ball given a red ball was already drawn) = (5/12) * (7/11) = 35/132

Ans: C

Let C be the number of carpenters, H be the number of chairs, and D be the number of days. The relationship is: C * D / H = constant. Thus, (12 * 16) / 20 = (24 * 8) / X, where X is the number of chairs. Solving for X, we get X = 20.

Ans: B

If the sum doubles in 4 years, then after another 4 years (total 8 years), it will double again (4 times the original). After another 4 years (total 12 years), it will double again (8 times the original).
