Correct answer
48
Why this answer is correct
BODMAS Table:
Given equation: {(48 ÷ 4) + (18 − 6)} × 2 = ?
⇒ {(48 ÷ 4) + (18 − 6)} × 2 = ?
⇒ {12 + (18 − 6)} × 2 = ?
⇒ {12 + 12} × 2 = ?
⇒ 24 × 2 = ?
⇒ 48.
Hence, the correct answer is "Option 4".

19
Correct answer
17
Why this answer is correct
BODMAS Table:
Given equation: 9 @ 5 ∗ 2 % 8 # 4 = ?
| @ | ∗ | % | # |
|---|---|---|---|
| + | × | − | ÷ |
Now, replacing the symbols:
⇒ 9 + 5 × 2 − 8 ÷ 4 = ?
⇒ 9 + 5 × 2 − 8 ÷ 4 = ?
⇒ 9 + 5 × 2 − 2 = ?
⇒ 9 + 10 − 2 = ?
⇒ 9 + 10 − 2 = ?
⇒ 19 − 2 = ?
⇒ 17.
Hence, the correct answer is "Option 1".
