Which one will replace the question mark ?
Answer: Option A
Explanation:
(2)2 = 4
(8)2 = 64
(5)2 = 25
(1)2 = 1.
Answer: Option B
(10 + 9 + 14 + 7)/2 = 20
and (11 + 16 + 10 + 13)/2 = 25
Therefore, (15 + ? + 12 + 10)/2 = 22
Hence 37 + ? = 44
? = 44 - 37
? = 7.
Answer: Option D
(5 x 6) + 2 = 32
(7 x 6) + 2 = 44
(7 x 5) + 2 = 37.
(5 + 3)/2 = 4
and (6 + 8)/2 = 7
Therefore (8 + 4)/2 = 6.
(1)2 + (5)2 + (4)2 + (3)2 = 51 x 10 = 510
and (3)2 + (4)2 + (6)2 + (2)2 = 65 x 10 = 650
Similarly (0)2 + (1)2 + (2)2 + (8)2 = 69 x 10 = 690.
