If + means − , − means × , × means ÷ , ÷ means +, what will come in place of the question mark (?) in the given equation?
99 × 33 – 70 ÷ 90 + 100 = ?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 200.
99 × 33 – 70 ÷ 90 + 100 = ?
After interchanging the mathematical sign we get;
= (99 ÷ 33) × 70 + 90 - 100
= 3 × 70 + 90 - 100
= 210 - 10
= 200
Hence, the correct answer is "200".
