Solution:

35

Explanation:
The value of RHS is
(A*A) - (A+A)

i.e
(2*2) - (2+2) = 4 - 4 = 00
(3*3) - (3+3) = 9 - 6 = 03
(4*4) - (4+4) = 16 - 8 = 08
(5*5) - (5+5) = 25 - 10 = 15
(6*6) - (6+6) = 36 - 12 = 24
(7*7) - (7+7) = 49 - 14 = 35

Solution:

24

8 + 8 / 2(1+3)= ?
8 + 8 / 2(4)= ?
8 + 4(4)= ?
8 + 16 = ?
24
