What will come in the place of the question mark (?) in the following equation, if '+' and '-' are interchanged and '×' and '÷' are interchanged?
9 ÷ 6 - 136 × 8 + 13 = ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 58.
Given equation: 9 ÷ 6 - 136 × 8 + 13 = ?
After interchanging signs equation becomes;
= 9 × 6 + (136 ÷ 8) - 13
= (9 × 6) + 17 - 13
= (54 + 17) - 13
= 71 - 13
= 58
