Question 2

Which of the statements given below are correct? 1. The author of the novel 'Fellside' is Victor LaValle. 2. The author of the novel 'A Head Full of Ghosts' is M.R Carey. 3. The author of the novel 'Brave New World' is Aldous Huxley.

Accepted Answer

Fellside is by M.R. Carey, A Head Full of Ghosts by Paul Tremblay, and Brave New World by Aldous Huxley. Only statement 3 is actually correct, despite the official key.

Question 3

The weights of 4 boxes are 20, 40, 50 and 30 kilograms. Which of the following cannot be the total weight, in kilograms, of any combination of these boxes and in a combination a box can be used only once?

Accepted Answer

The total weight of all boxes is 140 kg. To form 130 kg, we would need to exclude a 10 kg box, which doesn't exist. Thus, 130 kg is impossible.

Question 4

In triangle ABC, ∠ABC = 15o .D is a point on BC such that AD = BD. What is the measure of ∠ADC (in degrees)?

Accepted Answer

Since AD = BD, triangle ABD is isosceles, making ∠DAB = ∠DBA = 15°. The exterior angle ∠ADC equals the sum of interior opposite angles: 15° + 15° = 30°.

Question 5

If 6 * 9 – 4 = 58 and 3 * 9 – 7 = 34, then in the expression A * 4 – 9 = 91, what is the value of 'A'?

Accepted Answer

The pattern is (First × Second) + Third = Result. So, (A × 4) + 9 = 91. This gives 4A = 82, which means A = 20.5.

Question 6

Which of the following is the largest mammal?

Accepted Answer

The blue whale is the largest mammal, and indeed the largest animal, ever known to have lived on Earth, weighing up to 200 tons.

Question 7

If 3 @ 3 * 3 = 3 and 48 @ 4 * 3 = 36, then 91 @ 13 * 2 = ?

Accepted Answer

Replace '@' with division (÷) and '*' with multiplication (×). So, 91 ÷ 13 × 2 becomes 7 × 2 = 14.

Question 8

If Tan θ = 9/40, then Sec θ = ?

Accepted Answer

Tan θ = 9/40 means Perpendicular = 9, Base = 40. Hypotenuse = √(9² + 40²) = 41. Sec θ = Hypotenuse / Base = 41/40.

Question 9

The vocal cords in men are about _______ long.

Accepted Answer

Adult male vocal cords are typically between 17 mm and 25 mm in length, averaging about 20 mm. This larger size contributes to their deeper voice compared to women.

Question 10

The marked price of a sofa set is Rs 4800 which is sold at Rs 3672 at two successive discounts. If the first discount is 10%, then what will be the second discount (in %)?

Accepted Answer

Price after 1st discount = 4800 - 10% = 4320. Second discount amount = 4320 - 3672 = 648. Second discount % = (648 / 4320) × 100 = 15%.

Question 11

The ratio of present ages of R and S is 6:7. Before 12 years the ratio of their ages was 9:11. What is R's present age (in years)?

Accepted Answer

Let present ages be 6x and 7x. (6x - 12)/(7x - 12) = 9/11. Cross-multiplying gives 66x - 132 = 63x - 108, so 3x = 24, x = 8. R's age = 6(8) = 48.

Question 12

In the following question, select the missing number from the given series. 1357, 3085, 5282, 8026, ?

Accepted Answer

The differences between consecutive terms are cubes of consecutive numbers: 12^3 (1728), 13^3 (2197), and 14^3 (2744). The next difference is 15^3 = 3375. 8026 + 3375 = 11401.

Question 13

Supercooling is cooling of liquid _____.

Accepted Answer

Supercooling is the process of lowering the temperature of a liquid below its freezing point without it becoming a solid.

Question 14

From the given words, select the word which cannot be formed using the letters of the given word. THUMBING THUMBING

Accepted Answer

The original word 'THUMBING' does not contain the letter 'A'. Therefore, the word 'HAUNT' cannot be formed using its letters.

Question 15

What is the simpliﬁed value of (cosec A – sin A)(sec A – cos A)(tan A + cot A)?

Accepted Answer

Convert all terms to sin and cos. The expression becomes (cos²A/sinA) × (sin²A/cosA) × (1/(sinA cosA)). Multiplying these gives (sin²A cos²A)/(sin²A cos²A), which simplifies to 1.

Question 16

Bobby's birthday is on Monday 5th June. On what day of the week will be Pinky's Birthday in the same year if Pinky was born on 22nd September?

Accepted Answer

Calculate days from June 5 to Sept 22: 25 (June) + 31 (July) + 31 (Aug) + 22 (Sept) = 109 days. 109 ÷ 7 leaves a remainder of 4. Monday + 4 days = Friday.

Question 17

Priya's birthday is on Tuesday 11th April. On what day of the week will be Rani's Birthday in the same year if Rani was born on 31st August?

Accepted Answer

Total days from 11th April to 31st August = 19 (Apr) + 31 (May) + 30 (Jun) + 31 (Jul) + 31 (Aug) = 142 days. 142 ÷ 7 leaves remainder 2. Tuesday + 2 days = Thursday.

Question 18

In an examination 65% students pass in history and 55% students pass in hindi. If 5% students failed in both the subjects, then what is the percentage of students who have passed in both the subjects?

Accepted Answer

Total passed in at least one subject = 100% - 5% = 95%. Using set theory, passed in both = (65% + 55%) - 95% = 120% - 95% = 25%.

Question 19

In the following question, select the related letters from the given alternatives. HMPU : IOSY : : GMRF : ?

Accepted Answer

The pattern is +1, +2, +3, +4 for the respective letters. Applying this to GMRF gives G+1=H, M+2=O, R+3=U, F+4=J, resulting in HOUJ.

Question 20

The ratio of company's expenditure on Raw material and Transport to Salaries is:

Accepted Answer

Add the expenditure values for raw material and transport from the given data. Divide this sum by the expenditure on salaries to get the required ratio of 3:1.
