Sample Questions from this Test

Question 1:

The value of (42+(46+(3+(34+(4)))))\sqrt{\left(42+\sqrt{\left(46+\sqrt{\left(3+\sqrt{\left(34+\sqrt{(4)}\right)}\right)}\right)}\right)} is:
A.7
B.8
C.11
D.9

• Formula/Method: Apply the standard method for Nested Radicals to the given values.

• Key Step: Keep units and signs consistent throughout the calculation.

• Why the other options are wrong: They do not match the result from the given data.

• Final Answer: 7.

Question 2:

A question is followed by two statements numbered (I) and (II). You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements carefully and decide the appropriate answer.

Among 5 people, A, B, C, D and E, each of a different height, who is the second-tallest?
I: E is shorter than A. B is taller than D but shorter than E.
II: Only C is taller than A. D is shorter than E.
A.The data in statement II alone is sufficient to answer the question while data in statement I is not
B.The data in statement I alone is sufficient to answer the question while data in statement II is not
C.The data in statement I and II together (and not statement I alone or statement II alone) is sufficient to answer the question
D.The data in statement I and II put together is NOT sufficient to answer the question

• Deduction: Apply the clues or coding rule step by step and eliminate impossible cases.

• Exam Trick: Start with the most restrictive clue/pattern.

• Why the other options are wrong: They do not satisfy the complete set of conditions.

• Final Answer: The data in statement II alone is sufficient to answer the question while data in statement I is not.

Question 3:

Bleaching powder is commonly used:
A.As a sweetener
B.To make soap
C.To disinfect water
D.As a fuel

• Key Fact: The question tests the specific concept Disinfection and Bleaching Powder.

• Additional Fact: Remember the defining property or fact related to this topic.

• Why the other options are wrong: They refer to different concepts or do not satisfy the stated condition.

• Final Answer: To disinfect water.

Question 4:

Find the median of the following data.
7, 19, 88, 20, 19, 26, 90, 81, 44, 34.
A.30
B.32
C.28
D.34

• Median: Arrange the 10 values in ascending order: 7, 19, 19, 20, 26, 34, 44, 81, 88, 90.

• Formula: For even n, median = average of the 5th and 6th values = (26+34)/2 = 30.

• Final Answer: 30.

Question 5:

Atharv starts from Point A and drives 12 km towards west. He then takes a right turn, drives 3 km, turns right and drives 16 km. He then takes a right turn and drives 9 km. He takes a final right turn, drives 4 km and stops at Point P. How far (shortest distance) and towards which direction should he drive in order to reach Point A again?

(All turns are 90 degree turns only unless specified.)
A.5 km to the north
B.6 km to the north
C.5 km to the south
D.6 km to the south

• Direction Analysis: From A, the final point P is 6 km south of A. Therefore A lies 6 km north of P.

• Final Answer: 6 km to the north.

Question 6:

The Indian classical dance forms Kuchipudi and Bharatanatyam originated in which Indian states, respectively?
A.Andhra Pradesh and Tamil Nadu
B.Tamil Nadu and Andhra Pradesh
C.Kerala and Tamil Nadu
D.Karnataka and Andhra Pradesh

• Key Fact: The question tests the specific concept Indian Classical Dance Forms.

• Additional Fact: Remember the defining property or fact related to this topic.

• Why the other options are wrong: They refer to different concepts or do not satisfy the stated condition.

• Final Answer: Andhra Pradesh and Tamil Nadu.

Question 7:

A scientist is designing an artificial multi-cellular organism. What must they include to ensure all cells receive nutrients and remove wastes effectively?
A.A transportation system for food, oxygen, and waste
B.Only specialised tissues for nutrition
C.Direct contact of every cell with the environment
D.Simple diffusion through the entire surface

• Key Fact: The question tests the specific concept Transportation in Multicellular Organisms.

• Additional Fact: Remember the defining property or fact related to this topic.

• Why the other options are wrong: They refer to different concepts or do not satisfy the stated condition.

• Final Answer: A transportation system for food, oxygen, and waste.

Question 8:

Two water supply lines A and B can fill a reservoir individually in 10 hours and 12 hours, respectively. A discharge outlet D can empty the reservoir completely in 6 hours. If all three are opened together at 7:00 A.M., at what time will one-fourth of the reservoir be filled?
A.11 A.M.
B.10 P.M.
C.10 A.M.
D.11 P.M.

• Net Rate: 1/10 + 1/12 − 1/6 = 1/60 reservoir per hour.

• Time: One-fourth requires (1/4)×60 = 15 hours. Starting at 7:00 A.M., this is 10:00 P.M.

• Final Answer: 10 P.M.

Question 9:

If cosec⁡2θ+4sin⁡2θ=4\cosec^2\theta+4\sin^2\theta=4, where 0∘≤θ≤90∘0^\circ\le\theta\le90^\circ, then find the value of θ\theta.
A.90°
B.30°
C.45°
D.60°

• Trigonometric Step: Let s=sin²θ. Then cosec²θ=1/s. So 1/s+4s=4 ⇒ 4s²−4s+1=0 ⇒ (2s−1)²=0, hence s=1/2.

• Final Answer: θ=45°.

Question 10:

Anwar’s salary is ₹19,000 per month. He spends ₹4,500 on house rent, ₹1,500 on bills and the rest of the amount is his monthly savings. Find his savings (in ₹) in a year, if in the month of his birthday, he spent his complete monthly savings for his birthday celebration.
A.1,17,000
B.1,56,000
C.1,30,000
D.1,43,000

• Monthly Savings: 19000−4500−1500=₹13,000 per month.

• Birthday Month: In one month savings = ₹0, so annual savings = 11×13,000 = ₹1,43,000.

• Final Answer: ₹1,43,000.
