What will come in place of the question mark (?) in the following equation, if ‘+’ and ‘–’ are interchanged and ‘×’ and ‘÷’ are interchanged?
76 ÷ 6 + 18 × 6 – 49 = ?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 502.
Given expression: 76 ÷ 6 + 18 × 6 – 49 = ?
if ‘+’ and ‘–’ are interchanged and ‘×’ and ‘÷’ are interchanged:
76 × 6 - 18 ÷ 6 + 49 = ?
? = 76 × 6 - 3 + 49
? = 456 - 3 + 49 = 502
