8 + [16 – {7 + 4 – (9 of 3 + 6 – 4 × 7)}] =?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 18
Explanation:
According to the given question, using BODMAS, we get
8 + [16 – {7 + 4 – (9 of 3 + 6 – 4 × 7)}]
⇒ 8 + [16 – {7 + 4 – (27 + 6 – 4 × 7)}]
⇒ 8 + [16 – {7 + 4 – (27 + 6 – 28)}]
⇒ 8 + [16 – {7 + 4 – (33 – 28)}]
⇒ 8 + [16 – {7 + 4 – 5}]
⇒ 8 + [16 – {11– 5}]
⇒ 8 + [16 – 6]
⇒ 8 + [16 – 6]
⇒ 8 + 10 = 18
Hence the required answer is 18.
