Analyzing the given equations: We can put, A = + , B = - , C = ÷
30 A 10 B 30 C 10 = 37
30 + 10 - 30 ÷ 10 = 37
30 +10 – 3 = 37
40 – 3 = 37
37 = 37 (follows)
45 A 15 B 18 C9=58
45 + 15 - 18 ÷ 9=58
45 + 15 -2 = 58
60 – 2 = 58
58 = 58 (follows)
Similarly: following the same sign pattern
=64 + 34 - 50 ÷ 5
=64 + 34 -10
=64 + 24
=88
Thus, correct option is (b).
