What will come in the place of the question mark (?) in the following equation, if ‘+’ and ‘–’ are interchanged and ‘×’ and ‘÷’ are interchanged?
( 28 ÷ 4) – (15 × 3) + 48 = ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3, i.e., 69.
( 28 ÷ 4) – (15 × 3) + 48 = ?
After interchanging signs,
= ( 28 × 4) + (15 ÷ 3) - 48
= 112 + 5 - 48
= 117 - 48
= 69
