Correct Answer - Option 3 : 190

Given,

Given expression:

74 A (31 B 2) B 2 C (68 C 4) D (4 B 2) = ?

According to the question:

∴ 74 + (31 × 2) × 2 – (68 – 4) ÷ (4 × 2) = ?

Using the BODMAS rule,

74 + 62 × 2 – 64 ÷ 8 = ?

74 + 62 × 2 – 8 = ?

74 + 124 – 8 = ?

198 – 8 = ?

? = 190

**Hence, the correct answer is 190.**
