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.
Answer: Option C
(30 - 24) x 8 = 48
and (23 - 12) x 8 = 88
Therefore, (92 - 86) x 8 = 48.
9 + (2)2 = 13
13 + (3)2 = 22
22 + (4)2 = 38.
(15 + 12)/9 = 3
and (44 + 28)/9 = 8
Therefore, (64 + 53)/9 = 13.
(4 + 9 + 2) = (3 + 5 + 7) = (8 + 1 + 6)
Total in each case = 15.
All numbers are cubed,
(7)3 = 343
(1)3 = 1
(3)3 = 27
Similarly, (5)3 = 125.
