Which one will replace the question mark?

(18 x 12)/3 = 72

and (32 x 16)/4 = 128

Therefore, (24 x 14)/? = 112

(336/?) = 112

? = (336/112)

? = 3.

(3 x 4) + 3 = 15

and (7 x 5) + 3 = 38

Therefore (3 x 5) + 3 = 18.

(7 x 3) + 8 = 29

(4 x 3) + 7 = 19

(5 x ?) + 6 = 31

? = 5.

(16)² = 256

Therefore, (2)² = 4.

The numbers are squared in ascending order

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.

(2)³ + (1)³ + (3)³ = 36

and (0)³ + (4)³ + (3)³ = 91

Therefore, (4)³ + (2)³ + (1)³ = 73.

(30 - 24) x 8 = 48

and (23 - 12) x 8 = 88

Therefore, (92 - 86) x 8 = 48.

(6 + 5) - (7 + 4) = 0

and (7 + 6) - (8 + 4) = 1

Therefore (11 + 2) - (2 + 0) = 11.

Putting the position of the letters in reverse order

P = 11, S = 8, V = 5 and Y = 2.

(4 x 7) % 4 = 7

and (6 x 2) % 3 = 4

Therefore, (6 x 2) % 2 = 6.
