What will come in the place of the question mark (?) in the following equation, if ‘÷’ and ‘–’ are interchanged and ‘×’ and ‘+’ are interchanged?
[( 48 – 2) ÷ 23] × 19 + 3 = ?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4, i.e., 58.
[( 48 – 2) ÷ 23] × 19 + 3 = ?
After interchanging signs,
= [(48 ÷ 2) - 23] + 19 × 3
= [ 24 - 23] + 57
= 1 + 57
= 58
