Simplify the given expression:
[{9 × 81 + (142 ÷ 2)} + 350 - 155 + 5 ] ÷ [(25 × 25) - 125]
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e 2.
[{9 × 81 + (142 ÷ 2)} + 350 - 155 + 5] ÷ [(25 × 25) - 125]
⇒ [{9 × 81 + (71)} + 350 - 155 + 5] ÷ [(25 × 25) - 125]
⇒ [{729 + 71} + 350 - 155 + 5] ÷ [625 - 125]
⇒ [800 + 350 - 155 + 5] ÷ [500]
⇒ 1000/500 = 2
