What will come in the place of the question mark (?) in the following equation, if '+' and '-' are interchanged and '×' and '÷' are interchanged?
59 + 39 - 63 × 21 ÷ 26 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 98.
Given equation: 59 + 39 - 63 × 21 ÷ 26 = ?
if '+' and '-' are interchanged and '×' and '÷' are interchanged:
59 - 39 + (63 ÷ 21) × 26 = ?
? = 59 - 39 + (3 × 26)
? = 59 - 39 + 78
? = 137 - 39
? = 98
