What will come in place of the question mark (?) in the following equation, if ‘+’ and ‘-’ are interchanged and ‘×’ and ‘÷’ are interchanged?
107 + 2028 × 6 - 427 ÷ 7 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 2758.
Given equation: 107 + 2028 × 6 - 427 ÷ 7 = ?
After interchanging signs, the equation becomes:
107 - (2028 ÷ 6) + 427 × 7 = ?
= 107 - 338 + (427 × 7)
= 107 - 338 + 2989
= 3096 - 338
= 2758
