Correct Answer: JHFA

Solution : Let's check each option –
First option: JHFA; J – 2 = H; H – 2 = F; F – 5 = A
Second option: MKHD; M – 2 = K; K – 3 = H; H – 4 = D
Third option: XVSO; X – 2 = V; V – 3 = S; S – 4 = O
Fourth option: NLIE; N – 2 = L – 3 = I; I – 4 = E

So, the first option is different from the other three options because the difference in the place values of the letters is different. Hence, the first option is correct.

Correct Answer:

Solution : As per the mirror image properties, closer things appear close to the mirror in the reflection.
Here, according to the information provided, the mirror is placed on the right side of the figure. So, the left side of the reflected image will appear as the right side, and the right side will appear as the left side. However, the top and bottom of the reflected image will remain the same.
Thus, the correct mirror image of the given figure will be –

Hence, the fourth option is correct.

Correct Answer: 76, 67, 32, 68

Solution : Given:
SILK

Number representations of each letter –
S→95, 76, 57, 88, 69
I→55, 86, 67, 98, 79
L→20, 01, 32, 13, 44
K→75, 56, 87, 68, 99

Let's check the options –
First option: 76, 67, 33, 68 – L cannot be represented by 33.
Second option: 76, 66, 33, 68 – I and L cannot be represented as 66 and 33.
Third option: 76, 67, 32, 68 – All the letters of the word SILK can be represented through this option.
Fourth option: 76, 67, 32, 65 – K cannot be represented as 65.

So, only the third option consists of the numbers through which SILK can be represented. Hence, the third option is correct.

Correct Answer: 73

Solution : Given:
35 B 2 A 5 B (40 C 37) A (8 B 4) D 16 C 14 = ?

On replacing the letters with the mathematical signs as per the instructions given in the question, we get –
= 35 × 2 + 5 × (40 – 37) + (8 × 4) ÷ 16 – 14
= 35 × 2 + 5 × 3 + 32 ÷ 16 – 14
= 35 × 2 + 5 × 3 + 2 – 14
= 70 + 15 + 2 – 14
= 87 – 14 = 73

So, 73 is the required answer. Hence, the third option is correct.

Correct Answer:

Solution : Lets check the options to find a pattern.

First option: The dot is to the centre, the arrow is to the left of the dot and the line is to the right of the dot.
Second option: The arrow is to the right of the dot and the line is to the left of the dot.
Third option: The dot is to the centre, the arrow is to the left of the dot and the line is to the right of the dot.
Fourth option: The dot is to the centre, the arrow is to the left of the dot and the line is to the right of the dot.
So, the second option is the odd one out.
Hence, the second option is correct.

Correct Answer: 2

Solution : The correct choice is the second option.

• The word "signed" is incorrect in this context. It should be replaced with "sang" to make the sentence grammatically correct and convey the intended meaning.

• Sang is the past tense of the verb "sing", which means to produce musical sounds with the voice.

Therefore, the correct sentence should be: "The young child sang a very sweet song for the audience."
