What will come in place of the question mark (?) in the following equation if ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged?
16 ÷ 4 + 8 × 8 − 4 = ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 67.
Given equation: 16 ÷ 4 + 8 × 8 − 4 = ?
if ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged:
16 × 4 - 8 ÷ 8 + 4 = ?
? = 16 × 4 - 1 + 4
? = 64 - 1 + 4 = 67
