Q:

Consider a regular hexagon ABCDEF. Two towers are situated at B and C. The angle of elevation from A to the top of the tower at B is 30 deg, and the angle of elevation to the top of the tower at C is 45 deg. What is the ratio of the height of towers at B and C?

A) 1:√3 B) 1:3
C) 1:2 D) 1:2√3
 
Answer & Explanation Answer: B) 1:3

Explanation:

Let the side of regular hexagon be ‘a’

Let height of the tower 1 be h1 and tower 2 be h2

Height of tower 1 = h1 = (distance between A and B)* (tan 30o)= a.1/√3

Distance between A and C = 2*√3.a/2= √3a

Height of tower 2 = h2 = (distance between A and C)* (tan 45o) = √3a.1 = √3a

Ratio of height of towers at B and C respectively =a/√3/√3a = 1/3.

Q:

Sound travels fastest in

A) Vacuum B) Air
C) Glass D) Water
 
Answer & Explanation Answer: C) Glass

Explanation:

Sound is a mechanical vibration and needs a medium for propagation. The higher the density of the medium, the faster the sound travels. So, sound cannot travel through vacuum.

 

As the sound travels faster in solids than liquids and gases, sound travels faster in the glass than Air and water.

Q:

What happens during the process of translation?

A) Transfer RNA is made from messenger RNA B) Copies of DNA molecules are made
C) The cell uses information from messenger RNA to produce proteins D) Messenger RNA is made from DNA
 
Answer & Explanation Answer: C) The cell uses information from messenger RNA to produce proteins

Explanation:

Translation is the process by which a protein is synthesized from the information contained in a molecule of messenger RNA (mRNA). During translation, an mRNA sequence is read using the genetic code, which is a set of rules that defines how an mRNA sequence is to be translated into the 20-letter code of amino acids, which are the building blocks of proteins.

 

In short, during the process of translation source language text is conveyed to destination language.

Q:

An electronic device rearranges numbers step-by-step in a particular order according to set of rules. The device stops when the final result is obtained.


Input: 84 15 35 04 18 96 62 08
Step 1: 96 84 15 35 04 18 62 08
Step 2: 96 84 62 15 35 04 18 08
Step 3: 96 84 62 35 15 04 18 08
Step 4: 96 84 62 35 18 15 04 08
Step 5: 96 84 62 35 18 15 08 04
And Step 5 is the last step for this input. Now, find out an appropriate step in the following question following the above rule.

Question:
Input: 16 09 24 28 15 04
What will be the third step for this input ?

A) 28 24 15 16 04 09 B) 28 24 16 15 09 04
C) 24 28 15 16 09 04 D) 28 24 16 15 04 09
 
Answer & Explanation Answer: B) 28 24 16 15 09 04

Explanation:

Carefully obsrving the given arrangement, we find the following pattern:
We observe that the given numbers are arranged in descending order (from left to right), altering the position of only one number in each step, followed by the other numbers as it is. The process continues till the whole set of numbers is arranged in the descending order.

Step1: 28 16 09 24 15 04
Step2: 28 24 16 09 15 04
Step3: 28 24 16 15 09 04

Hence, the answer is B

Q:

In the given number series which follows the definite rules then find out the value of (M, N, O, and P) in second number series.

7  18  42  94  204

4   M   N    O     P

What value will come in place of P?

A) 179 B) 184
C) 164 D) 156
 
Answer & Explanation Answer: D) 156

Explanation:

Here the given series 7  18  42  94  204 follows a pattern that, 

7

×2+4 = 18

18 ×2+6 = 42

42 ×2+10 = 94

94 ×2+16 = 204

Similarly,

4

×2+4 = 12

12 ×2+6 = 30

30 ×2+10 = 70

70 ×2+16 = 156

Hence, the value of P = 156.

Q:

The molecular mass of sulphuric acid is 98. If 49 g of the acid is dissolved in water to make one litre of solution, what will be the strength of the acid?

A) Two normal B) One normal
C) 0.5 normal D) Four normal
 
Answer & Explanation Answer: B) One normal

Explanation:

Normality is a way of expressing concentration of a solution and can be calculated by the formula-

Normality (N) = No. of gram equivalent of solute/ volume of solution (in litre)

Gram equivalent weight of H2 SO4 = Molecular weight/ No. of Hydrogen atom = 98/2 = 49 gm

No. of gram equivalent in 49 gm of H2 SO4 = 1

So, Normality in 1 litre of solution = 1/1 = 1 N
