Explanation:-
3 x 3 + 2 x 2 + 1 x 1 = 9 + 4 + 1
= 14,
4 x 4 + 3 x 3 + 2 x 2 = 16 + 9 + 4
= 29

Similarly,
5 x 5 + 4 x 4 + 3 x 3 = 25 + 16 + 9
50

Then, the value of ? is 50.

Hence, the correct answer is option (c) 50.

Explanation:-
8 x 4 = 32/2 = 12,
6 x 4 = 24/2 = 12,

Similarly,
9 x 8 = 72/2 = 36.

Then, the value of ? is 72.

Hence, the correct answer is option (b) 72.
