Question

Select the related number from the given alternatives that will complete the series:
Y$^2$ : 4 :: V$^2$ : ___

• A. 49
• B. 25
• C. 16
• D. 9

Hint:

In such questions, try \textbf{digit sum} or repeated digit reduction after applying operations.

Answer 1

The Correct Option is D

Concept: This problem involves converting letters into their alphabet positions, squaring them, and then reducing the result using digit-sum patterns. Step 1:Compute value for Y.
\[ Y = 25 \] \[ Y^2 = 25^2 = 625 \] Reduce using digit sum: \[ 6 + 2 + 5 = 13,\quad 1 + 3 = 4 \] So, \[ Y \rightarrow 4 \]
Step 2:Apply same method to V.
\[ V = 22 \] \[ V^2 = 22^2 = 484 \] Reduce using digit sum: \[ 4 + 8 + 4 = 16,\quad 1 + 6 = 7 \] So, \[ V \rightarrow 7 \]
Step 3:Final Answer: \[ 7 \]
