and 6 x 9 x 7 = 378
Therefore 5 x 7 x ? = 315
? = 9.
In first circle,
(3)2 = 9
(4)2 = 16
(5)2 = 25
(6)2 = 36.
In second circle,
(4)2 = 16
(5)2 = 25
(6)2 = 36
(7)2 = 49.
In third circle,
(6)2 = 36
(7)2 = 49
(8)2 = 64
(9)2 = 81.
Therefore, (2)2 = 4.
(4 x 3) + 7 = 19
(5 x ?) + 6 = 31
? = 5.
and (7 x 5) + 3 = 38
Therefore (3 x 5) + 3 = 18.
and (32 x 16)/4 = 128
Therefore, (24 x 14)/? = 112
(336/?) = 112
? = (336/112)
? = 3.
(28 - 12) + (16 - 20) = 12
Similarly, (23 -11) + (15- 16) = 11.
and (0)3 + (4)3 + (3)3 = 91
Therefore, (4)3 + (2)3 + (1)3 = 73.
and (23 - 12) x 8 = 88
Therefore, (92 - 86) x 8 = 48.
and (7 + 6) - (8 + 4) = 1
Therefore (11 + 2) - (2 + 0) = 11.
