Correct Answer: $3 \frac{1}{4}$

Solution : Given: $[\frac{85}{34}×\frac{1}{18}–${${{(\frac{46}{69}÷\frac{27}{135})}}–(\frac{86}{129}×\frac{91}{14})$} of $\frac{112}{36}]$
$=[\frac{85}{34}×\frac{1}{18}–${${{(\frac{46}{69}×\frac{135}{27})}}–(\frac{86}{129}×\frac{91}{14})$} of $\frac{112}{36}]$
$=[\frac{5}{2}×\frac{1}{18}–${${{(\frac{2}{3}×\frac{5}{1})}}–(\frac{1}{3}×\frac{13}{1})$} of $\frac{28}{9}]$
$=[\frac{5}{36}–${${{\frac{10}{3}}}–\frac{13}{3}$} ×$\frac{28}{9}]$
$=[\frac{5}{36}+{\frac{3}{3}}×\frac{28}{9}]$
$=[\frac{5}{36}+\frac{28}{9}]$
$=[\frac{5+112}{36}]$
$=\frac{117}{36} = 3 \frac{1}{4}$
Hence, the correct answer is $3 \frac{1}{4}$.

Narration Conversion:

• The reporting verb told is changed to said in the direct form.
• The third-person pronoun she in the reported speech becomes I in the direct speech when quoting the speaker directly.
• The simple past tense (knew) is changed to the simple present tense (know) in direct speech.
• The words of the speaker are enclosed in quotation marks.

Therefore, the correct sentence in the direct form is: She said to me, “I know you want to help me, but I can manage on my own.”

Correct Answer: 16 : 64 

Solution : Let's check the options –
First option: 81 – 243→81 × 3 = 243
Second option: 16 – 64→16 × 3 = 48 ≠ 64
Third option: 64 – 192→64 × 3 = 192
Fourth option: 25 – 75→25 × 3 = 75

Hence, the second option is correct.

Correct Answer: which

Solution : The correct choice is the fourth option.

Using which here connects the sentence logically, indicating that the developed nations were affected by these specific technological breakthroughs, making it the suitable choice to maintain coherence in the sentence.

Correct Answer: PRSQ

Solution : The second option is the correct answer.

It starts by presenting the decision not to include any kind of wealth or income tax (P). Following this, it introduces the alternative solution of implementing an income tax, which is suggested to be a fairer option for addressing the social care funding crisis (R). The sentence then specifies the purpose of this alternative, emphasising that it aims to solve the social care funding crisis (S). Finally, the sentence concludes by stating that this decision has proven controversial (Q).

Therefore, the correct answer is PRSQ.

Correct Answer: 6 and 5, – and ×

Solution : Given:
18 – 6 + 11 × 5 + 18 = 113

Replace the symbols and numbers given in the equation with the assigned symbols and numbers in the options one by one –
First option: 6 and 5, + and ×
⇒ 18 – 5 × 11 + 6 × 18 = 113
Solving the L.H.S of the equation –
= 18 – 5 × 11 + 6 × 18
= 18 – 55 + 108
= 71 ≠ 113
Second option: 18 and 5, + and ×
⇒ 5 – 6 × 11 + 18 × 5 = 113
Solving the L.H.S of the equation –
= 5 – 6 × 11 + 18 × 5
= 5 – 66 + 90
= 95 – 66
= 29 ≠ 113
Third option: 6 and 5, – and ×
⇒ 18 × 5 + 11 – 6 + 18 = 113
Solving the L.H.S of the equation –
= 18 × 5 + 11 – 6 + 18
= 90 + 11 – 6 + 18
= 119 – 6
= 113
Fourth option: 18 and 5, – and ×
⇒ 5 × 6 + 11 – 18 + 5 = 113
Solving the L.H.S of the equation –
= 5 × 6 + 11 – 18 + 5
= 30 + 11 – 18 + 5
= 46 – 18
= 28 ≠ 113

So, only the third option satisfies the equation. Hence, the third option is correct.

Correct Answer: NCWN

Solution : Given:
NMQR, NQYD, NUGP, NYOB, ?

In the given series, the first letter (N) is constant. Add 4, 8, and 12 to the place value of the first, second, third, and fourth letters.
NMQR→N; M + 4 = Q; Q + 8 = Y; R + 12 = D
NQYD→N; Q + 4 = U; Y + 8 = G; D + 12 = P
NUGP→N; U + 4 = Y; G + 8 = O; P + 12 = B
NYOB→N; Y + 4 = C; O + 8 = W; B + 12 = N

So, the missing term is NCWN. Hence, the third option is correct.
