What will come in the place of the question mark (?) in the following equation, if ‘+’ and ‘÷‘ are interchanged and ‘-’ and ‘×’ are interchanged?
16 - 2 × 104 + 4 ÷ 20 = ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 26.
Given equation: 16 - 2 × 104 + 4 ÷ 20 = ?
After interchanging the signs:
(16 × 2) - (104 ÷ 4) + 20 = ?
= 32 - 26 + 20
= 52 - 26
= 26
