Show answer & explanation

Correct answer: A

Explanation

The correct answer is Option 1 i.e. 78.

On applying the BODMAS Rule
197−[19197-[\frac{1}{9}{42 + (56 - 8 + 9)} + 108]

⇒ 197−[19197-[\frac{1}{9}{42 + (57)} + 108]

⇒ 197−[19197-[\frac{1}{9}{99} + 108]

⇒ 197−[11+108]197-[{11} + 108]

⇒ 197−[119]197-[119] = 78
