What will come in the place of the question mark (?) in the following equation, if '+' and '-' are interchanged and '×' and '÷' are interchanged?
800 × 16 - 8 ÷ 12 + 18 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 128.
Given equation: 800 × 16 - 8 ÷ 12 + 18 = ?
if '+' and '-' are interchanged and '×' and '÷' are interchanged:
800 ÷ 16 + 8 × 12 - 18 = ?
? = 50 + 96 - 18
? = 146 - 18 = 128
