162 - 52 ÷ 26 + 15 x 5
= 162 - 2 + 75 = 235Correct Option: B
162 - 52 ÷ 26 + 15 x 5
= 162 - 2 + 75 = 235

40 + 12 ÷ 3 x 6 - 60
= 40 + 4 x 6 - 60
= 40 + 24 - 60
= 64 - 60 = 4Correct Option: D
40 + 12 ÷ 3 x 6 - 60
= 40 + 4 x 6 - 60
= 40 + 24 - 60
= 64 - 60 = 4

The given expression is 42*4*12*9 = 0
From option (c), 42, - 4 ÷ 12 x 20 + 9
By coding, the equation becomes,
LHS ⇒ 42 x 4 + 12 ÷ 20 - 9
By applying the operations in sequence, from left to right,
168 + 12 ÷ 20 - 9
180 ÷ 20 - 9
9 - 9 = 0 = R.H.S.Correct Option: C
