Answer: Option D
Explanation:
(5 + 4 + 7)/2 = 8
(6 + 9 + 5)/2 = 10
(3 + 7 + 2)/2 = 6.
Answer: Option C
(12 + 18 + 30)/10 = 6
(16 + 24 + 40)/10 = 8
Similarly, (45 + 18 + 27)/10 = 9.
(5 x 3) + 4 = 19
and (6 x 4) + 5 = 29
Therefore, (7 x 5) + 6 = 41
Answer: Option A
(15 x 2 - 3) = 27,
(31 x 2 - 6) = 56
and (45 x 2 - 9) = 81
Answer: Option B
(5 x 6 x 8) + (7 x 4 x 9) = 492
and (7 x 5 x 4) + (6 x 8 x 9) = 572
Therefore (4 x 3 x 5) + (7 x 2 x 5) = 130.
21 + 31 = 52
and 39 + 46 = 85
Therefore, 16 + 83 = 99.
(18 x 12)/3 = 72
and (32 x 16)/4 = 128
Therefore, (24 x 14)/? = 112
(336/?) = 112
? = (336/112)
? = 3.
(0 + 2 + 6 + 4) - 2 = 10
and (6 + 2 + 10 + 8) - 2 = 24
Therefore, (4 + 14 + 12 + 10) - 2 = 38.
(1)3 = 1, (2)3 = 8, (3)3 = 27
Therefore, (4)3 = 64.
Sum of numbers in lower half of the circle = 11 + 9 + 3 + 7 = 30
Sum of numbers in upper half of the circle = ? + 4 + 5 + 6 = ? + 15
Upper half = Lower half
30 = ? + 15
? = 30 - 15
? = 15.
Threfore, 15 is the answer.
