Simplify 63 - [15 + {17 - (9 - 7 + 1)}].
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 34.
Given that, 63 - [15 + {17 - (9 - 7 + 1)}]
Applying the rule of BODMAS,
⇒ 63 - [15 + {17 - (10 - 7)}]
⇒ 63 - [15 + {17 - 3}]
⇒ 63 - [15 + 14]
⇒ 63 - 29 = 34
Hence the required answer is 34.
