What will come in place of the question mark (?) in the following equation if ‘+’ and ‘ב are interchanged and ‘−’ and ‘÷’ are interchanged?
27 − 6 + 4 × 8 ÷ 6 = ?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 20.
Given equation: 27 − 6 + 4 × 8 ÷ 6 = ?
if ‘+’ and ‘ב are interchanged and ‘−’ and ‘÷’ are interchanged:
27 ÷ 6 × 4 + 8 - 6 = ?
? = 18 + 8 - 6
? = 26 - 6
? = 20
