A163

B86

C136

D190

Answer:

C. 136

Read Explanation:

We are given the expression:

39÷324+60×1239 ÷ 3 - 24 + 60 × 12

Interchange the operators

  • ‘+’ ↔ ‘−’

  • ‘×’ ↔ ‘÷’

So the modified expression becomes:

39×3+2460÷1239 × 3 + 24 - 60 ÷ 12

Apply BODMAS

39×3=11739 × 3 = 117

60÷12=560 ÷ 12 = 5

Now substitute:
117+245117 + 24 - 5
= 136
