Simplify:
13 – [7 – (4 + 7) – {7 – (7 – 4 + 7)} + 14]
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 0.
According to the given question,
13 – [7 – (4 + 7) – {7 – (7 – 4 + 7)} + 14]
⇒ 13 – [7 – 11 – {7 – 10} + 14]
⇒ 13 – [7 – 11 + 3 + 14]
⇒ 13 – [24 - 11]
⇒ 13 – 13 = 0
Hence the required answer is 0.
