Simplify the given expression.
4 × 5 ÷ 4 of 5 × 4 ÷ ( 6 + 6 × 6 ÷ 6 of 6 - 6 ÷ 6 × 6 )
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 4.
According to the given question,
4 × 5 ÷ 4 of 5 × 4 ÷ ( 6 + 6 × 6 ÷ 6 of 6 - 6 ÷ 6 × 6 )
Applying the rule of BODMAS,
4 × 5 ÷ 4 of 5 × 4 ÷ ( 6 + 6 × 6 ÷ 6 of 6 - 6 ÷ 6 × 6)
⇒ 4 × 5 ÷ 4 of 5 × 4 ÷ ( 6 + 6 × 6 ÷ 36 - 6 ÷ 6 × 6)
⇒ 4 × 5 ÷ 4 of 5 × 4 ÷ ( 6 + 1 - 1 × 6)
⇒ 4 × 5 ÷ 4 of 5 × 4 ÷ ( 6 + 1 - 6)'
⇒ 4 × 5 ÷ 4 of 5 × 4 ÷ 1
⇒ 4 × 5 ÷ 20 × 4
⇒ 1 × 4 = 4
Hence the required answer is 4.
