What will come in the place of ‘?’ in the following equation, if ‘+’ and ‘ – ‘ are interchanged and ‘x’ and ‘÷’ are interchanged?
18 ÷ 3 + 12 x 6 – 4 = ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 56.
Given equation: 18 ÷ 3 + 12 × 6 – 4 = ?

18 × 3 - 12 ÷ 6 + 4 = ?
? = 54 - 2 + 4
? = 58 - 2 = 56
