100 ÷ 10 - [-2 + {-9 + (3 - 6 of 2)}] = ________
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 30.
Given, 100 ÷ 10 - [-2 + {-9 + (3 - 6 of 2)}]
⇒ 100 ÷ 10 - [-2 + {-9 + (3 - 12)}]
⇒ 100 ÷ 10 - [-2 + {-9 - 9)}]
⇒ 100 ÷ 10 - [-2 -18}]
⇒ 100 ÷ 10 + 20
⇒ 10 + 20 = 30
