Which one will replace the question mark ?
Answer: Option B
Explanation:
(2)2 + (4)2 = 20
and (3)2 + (9)2 = 90
Therefore (1)2 + (5)2 = 26.
(7 x 3) = 21 and (9 x 3) = 27
and (4 x 9) = 36 and (2 x 9) = 18
Therefore (9 x 6) = 54 and (4 x 6) = 24.
(16 + 13) = (14 + 15)
and (28 + 12) = (10 + 30)
Therefore (29 + 16) = (15 + 30).
Answer: Option D
(3 x 4) + 3 = 15
and (7 x 5) + 3 = 38
Therefore (3 x 5) + 3 = 18.
Answer: Option A
(15 - 12) + (10 - 9) = 4
(28 - 12) + (16 - 20) = 12
Similarly, (23 -11) + (15- 16) = 11.
