What will come in place of the ‘?’ in the following equation, if ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged?
56 + 12 − 54 × 18 ÷ 6 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 62.
Given equation: 56 + 12 − 54 × 18 ÷ 6 = ?
When ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged, then
= 56 - 12 + 54 ÷ 18 × 6
= 56 - 12 + 3 × 6
= 56 - 12 + 18
= 74 - 12
= 62
