What will come in the place of the question mark (?) in the following equation, if ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged?
2 ÷ 40 × 5 – 4 + 5 = ?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 15.
Given equation: 2 ÷ 40 × 5 – 4 + 5 = ?
