6/2 = 3
11 * 2 = 22
=> 22 + 3 = 25

8/2 = 4
6 * 2 = 12
=> 4 + 12 = 16

Similarly;
12/2 = 6
5 * 2 = 10
=> 10 + 6 = 16.
Then, 12 5 16.

(3+0)*5=15
(1+8)*9=81
(2+7)*7=63

35+20+28-43=40
28+11+16-35=20
25+35+40-32=68
So answer is 68

C. 86 is the right answer. Bcz, 30-24=6. 6×8=48. =>23-12=11. 11×8=88. .. .. Then, also 92-86=6. =>6×8=48

7+5 = 12 /2 = 6
5+21=26/2=13
21+7=28/2=14
