What is the value of 3[4 + 2{42 − 4(9 − 1)}]?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 72.
According to the given question,
3[4 + 2{42 − 4(9 − 1)}]
Applying the rule of BODMAS,
⇒ 3[4 + 2{42 − 4(9 − 1)}]
⇒ 3[4 + 2{42 − 4 × 8}]
⇒ 3[4 + 2 × 10]
⇒ 3[4 + 20]
⇒ 3 × 24 = 72
Hence the required answer is 72.
