Sasthamcotta Lake is located in Kerala.

* Sasthamcotta Lake is also categorized as a Wetland Site under Ramsar Convention.

* Sasthamcotta Lake is located near Quilon city in Kerala.

* It is the largest fresh water lake in Kerala.

* Other Important lakes of Kerala are Vembanand, Periyar, Asthamudi, Vellayani, Pookode, etc.

The purpose of committees given in option are-

* Pannir Selvam Committee was appointed to give a detailed report on the Non Performing Assets of public sector banks.

* Melagam Committee was constituted by RBI to monitor bad loans, rising cases of frauds and audits.

* Srikrishna Committee was constituted for data protection.

* Mandal Committee was formed to "identify the socially or educationally backward classes" of India.

The terms systolic and diastolic are used in the context of measuring blood pressure.

* Blood pressure is measured using two numbers. For ex. “120/80 mmHg.”

* The first number is called systolic blood pressure which measures the pressure in your blood vessels when your heart beats.

* The second number is called diastolic blood pressure which measures the pressure in your blood vessels when your heart rests between beats.

To make the given equation correct, × and ÷ should be interchanged.

 28 – 42 × 2 + 276 ÷ 23 (Applying BODMAS)

= 28 – 42 × 2 + 12

= 28 – 84 + 12

= 40 – 84

= –44

Hence, option D is the correct response.

The least possible Venn diagram will be:

Conclusions:
I. Some tractors are cups – (false) as there is no direct relation between tractors and cups therefore we can't say.
II. No jar is boat – (false) as it is not a definite case.
III. Some cups are jars – (false) as there is no direct relation between cups and jars; therefore, we can't say.
So, none of the conclusions follows.

Hence, option C is correct response.

The pattern is – adbca

The complete series is – adbca/adbca/adbca/adbca.

Hence, option C is the correct response.

We are given that the quadrilateral PQRS is cyclic.

So we know the sum of opposite angles of cyclic quadrilateral is 180°.

So we have

∠P + ∠R = 180° …….. eq 1

∠S + ∠Q = 180° ……… eq 2

Given that:

∠P = 4 ∠R

∠S = 3 ∠Q

We have from eq1

And

Also by eq2

And

Sum = Q + R = 45° + 36° = 81°

Given:

x⁴ – 5x² – 1 = 0

 …. eq. 1

Now we have to find the value of:

Using eq(1):

We have the value of

= 140

Putting it in the above equation:

140 - 3(5) + 1

= 140 – 14 = 126

The length of train = 360m

Time = t₁ = 55 sec

Time = t₂ = 24 sec

Now

speed=distance/time

s=360/24=15m/s

Now the distance will be given by:

Distance = speed × time

d=15×55=825 m

The length of the platform is given: (total distance – length of train)

= 825 – 360

= 465 m

 Remote is the most appropriate word to fill in the blank. It means not easily accessible. The later part of the sentence gives us a hint that it is the less visited place due to its remote location. Other words fail to provide any contextual meaning to the given sentence.

Hence, option C is the correct choice.

Enthral means to capture and hold one's attention; fascinate or mesmerise. Mesmerise is the most appropriate synonym of the given word.

Disgust and Repel mean strong dislike.

Free means costing nothing.

Hence, option C is the correct choice.

 The crux of the matter corresponds to the basic, central or critical point of an issue or the heart of the matter.

For eg: As usual, the power was at the crux of the matter.

Hence, option C is the correct choice.
