a² + b² + c² + 108 = 12(a − b − c)
a² − 12a + 36 + b² + 12b + 36 + c² + 12c + 36 = 0
(a − 6)²+(b + 6)²+(c + 6)² = 0

If and Only if
a − 6 = 0, b + 6 = 0 and c + 6 = 0
⇒ a = 6, b = −6, c = −6

2 of 3 ÷ 3 × 2 + {4 × 3 – (5 ÷ 2 + 3)}

=6÷ 3× 2 +{12-(11/2) } = 2× 2+{13/2}

= 4 + 13/2 = 21/2

Frivolous = not serious in content, attitude or behaviour.

The given sentence is grammatically incorrect and the error lies in option A.

• The error is in the use of the adverb 'hardly'.

• The use of "does not" is incorrect in the sentence as the word "hardly" already gives negative meaning to the sentence.

• "Hardly" means only just, almost not.

• Thus, remove 'does not' to make the sentence grammatically correct.

• In order to arrange the given sentences in an orderly manner, we need to find the theme.

• The first sentence will be Q as it introduces the main theme i.e., 'the species of pinnipeds'. Sentence Q leads the introductory information about pinnipeds or seals.

• After this, next will be sentence P that elaborates the specialty of the pinnipeds in spite of belonging to different species.

• Sentence S will be the third one in the sequence as it further explains the term.

• The last sentence will be R, which concludes the given sentences i.e., it is concerned with analyzing known clinical abnormalities.

• Thus, the correct sequence is QPSR.

After arranging the sequence would be:- "There are 33 species of pinnipeds alive today, most of which are known as seals. While there are many differences among the species, all seals have feet shaped like fins. In fact, the word pinniped means "fin-footed" in Latin. Those fin-shaped feet make them supreme swimmers, and all pinnipeds are considered semi-aquatic marine mammals." 

Hence, option B is the correct answer.
