Correct Answer: JLN

Solution : Let's check each option –
First option: JLN; J + 2 = L; L + 2 = N
Second option: MOR; M + 2 = O; O + 3 = R
Third option: CEH; C + 2 = E; E + 3 = H
Fourth option: VXA; V + 2 = X; X + 3 = A

So, the first option does not follow the pattern as the difference between the second and third letters is 2 instead of 3. Hence, the first option is correct.

Correct Answer: Rs. 12,000

Solution : Given that investment by X, Y, and Z = Rs. 4,000, Rs. 6,000, and Rs. 8,000 respectively
The period they invested for 3, 2, and 4 years respectively.
Total profit = Rs. 56000
Profit of X : Profit of Y : Profit of Z $= 4000 × 3: 6000 × 2: 8000 × 4$
⇒ Profit of X : Profit of Y : Profit of Z $= 3: 3: 8$
⇒ Y's share $= \small\frac{\text{Profit of Y}}{\text{Total Profit}} × 56000$
⇒ Y's share $= \frac{3}{14}× 56000 =12000$
Hence, the correct answer is Rs. 12,000.
