[25 − 48 ÷ 6 + 12 × 2] + 78 − [5 + 3 × (25 − 2 × 10)]
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 99.
[25 − 48 ÷ 6 + 12 × 2] + 78 − [5 + 3 × (25 − 2 × 10)]
⇒ [25 − 8 + 24] + 78 − [5 + 3 × (25 − 20)]
⇒ [49 - 8] + 78 − [5 + 3 × 5]
⇒ [49 - 8] + 78 − [5 + 15]
⇒ 41 + 78 − 20 = 99
