The correct answer is Option 1 i.e  694\frac{69}{4}​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​.

1 - 3 ÷ 6 of 2 + (4 ÷ 4 of 1/4) ÷ 8 + (4 × 8 ÷ 1/4) × 1/8

Applying BODMAS

⇒ 1 - 3 ÷ 12 + (4 ÷ 1) ÷ 8 + (4 × 8 ÷ 1/4) × 1/8

⇒ 1 - 1/4 + 4 ÷ 8 + (4 × 8 × 4) × 1/8

⇒ 1 - 1/4 + 1/2 + 16

⇒ 17 - 1/4 + 1/2

⇒ 68/4 - 1/4 + 2/4

⇒ 694\frac{69}{4}
