Hence, ‘25’ will be placed at the sign of question mark (?) to complete the given matrix.

Present age of P = 45 yrs.

Let present age of Q be x yrs.

After nine years, age of P = 45 + 9 = 54 yrs.

After nine years, age of Q = (x + 9) yrs.

After nine years, ratio of ages of P and Q = 6 : 7 = $\frac{6}{7}$

After nine years, ratio of ages of P and Q = $\frac{{54}}{{{\rm{x}} + {\rm{}}9}}$

On comparing both the above equation, we get

→ $\frac{6}{7} = \frac{{54}}{{{\rm{x}} + {\rm{}}9}}$

→ 6 (x + 9) = 54 × 7

→ 6x + 54 = 378

→ 6x = 324

→ x = 54

Hence, the present age of Q is 54 yrs.

Persons: P, Q, R, S and T.

Given: P, Q, R, S and T are sitting in a line facing west.

1. R is sitting at south end and S is sitting at north end.

2. T is neighbour of Q and R.

3. P and Q sit at adjacent places.

Hence, P is second from the North end.

1. Weight of P is twice that of Q.

→ P = 2Q       ----(i)

2. Weight of Q is half of R.

→ Q = R/2      ----(ii)

3. Weight of R is 3 times of T.

→ R = 3T       ----(iii)

4. Weight of T is half of S.

→ T = S/2        ----(iv)

From (i) and (ii)

P = 2Q = 2 × R/2 = R

So, P = 2Q = R

Now, R = 3T and T = S/2

So, R = 3 × S/2

On equating each equation, we get

P = 2Q = R = 3T = 3S/2

or P = R = 2Q = 3T = 3S/2

∴ P = R and other are smaller that P and Q

Hence, either P or R is the heaviest.

The error lies in part 3 of the sentence. The word ‘are’ should be changed to ‘is’ since the subject is collective and should be considered as singular.

The correct answer is option 1.

The noun 'vacation' can be both countable or uncountable. 

But in more specific contexts, the plural form 'vacations' should be used. 

Hence the correct sentence is:

Our summer vacations are from 10^th May to 10^th June.

The error in the sentence lies in part 3. The word ‘have’ should be changed to ‘has’ to make the sentence grammatically correct.

The error in the sentence lies in part 3. Since ‘picnic’ is a specific occasion therefore the article ‘the’ should be used before the word ‘picnic’.

The correct answer is '3' i.e. error lies in part 3 of the sentence.

Key Points

In part 3 of the sentence, the usage of 'to' is incorrect Omit 'to'

• 'On my way back' is a phrase that means 'returning on the path home'
• Let's see an example-
• I stopped for a drink on my way back home from work

So the correct sentence is→ I met the gentleman today evening on my way back home.

The correct answer is Option 4 i.e. 'No error'

Key Points

The given sentence is a conditional sentence of 'Imaginary sentence'.

• The conditional sentences are those sentences in which condition is given in the 'If' clause. 'If' clause is a subordinate clause and there is one main clause.
• The structure of imaginary sentences in a conditional sentences are 'If + Subject + present subjunctive mood (were) + Object + Main clause.'
• In this sentence, 'I' is a subject and 'were' is a linking verb hence we need to write a subject complement it should be noun/pronoun/adjective and In this case subject complement should agree with the subject. Hence, that's why 'he' is written not 'him.'
• Let's see an example:
• If I were he I would think twice before cutting his hair.

So the correct sentence is:

If I were he I wouldn't accept the offer.
