What will come in place of ‘?’ in the following equation, if ‘+’ and ‘–‘ are interchanged and ‘×’ and ‘÷’ are interchanged?
617 ÷ 3 − 84 + 515 × 5 = ?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 1832.
617 ÷ 3 − 84 + 515 × 5 = ?
After interchanging signs,
= 617 × 3 + 84 - (515 ÷ 5)
= 617 × 3 + 84 - 103
= 1851 + 84 - 103
= 1935 - 103
= 1832
