Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 100.
According to the given question,
[{70 − 60÷ 2 of 6} + (20− 10)÷ 10] + 600÷ 25 of (2 ×3)× (2 of 3) + 2 of 5
Applying the rule of BODMAS,
⇒ [{70 − 60÷ 2 of 6} + 10 ÷ 10] + 600 ÷ 25 of 6 × 6 + 2 of 5
⇒ [{70 − 60 ÷ 12} + 10 ÷ 10] + 600 ÷ 25 of 6 × 6 + 2 of 5
⇒ [{70 − 5} + 10 ÷ 10] + 600 ÷ 25 of 6 × 6 + 2 of 5
⇒ [65 + 10 ÷ 10] + 600 ÷ 25 of 6 × 6 + 2 of 5
⇒ [65 + 1] + 600 ÷ 25 of 6 × 6 + 2 of 5
⇒ 66 + 600 ÷ 25 of 6 × 6 + 2 of 5
⇒ 66 + 4 × 6 + 10
⇒ 66 + 24 + 10 = 100
Hence the required answer is 100.
