Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 46.
66 − 2 × [10 + 2 × {18 − 2 × (7 − 4) × 3} ÷ 50]
= 66 − 2 × [10 + 2 × {18 − 2 × 3 × 3} ÷ 50]
= 66 − 2 × [10 + 2 × {18 − 18} ÷ 50]
= 66 − 2 × [10 + 2 × 0 ÷ 50]
= 66 − 2 × [10 + 0]
= 66 − 2 × 10
= 66 − 20
= 46
