What will come in the place of ?' in the following equation, if '+' and '-' are interchanged and '×' and '÷' are interchanged?
15 ÷ 5 + 12 × 3 - 5 = ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 76.
Given : 15 ÷ 5 + 12 × 3 - 5 = ?
If '+' and '-' are interchanged and '×' and '÷' are interchanged, the equation will be :
= (15 × 5) - (12 ÷ 3) + 5
= (15 × 5) - 4 + 5
= 75 - 4 + 5
= 80 - 4
= 76
