Question

In the following table replace the question mark (?) from the alternatives given below

7	2	53
3	6	45
5	4	?

• A. 39
• B. 41
• C. 51
• D. 63

Answer 1

The correct option is B 41

In first row, $7^2+2^2=49+4=53$ the last cell value.

In $2^{nd}$ row, $3^2+6^2=9+36=45$.

In $3^{rd}$ row, $5^2+4^2=25+16=41$.

Hence, $41$ replaces question mark.
