What will come in the place of ‘?’ in the following equation, if ‘÷’ and ‘–‘ are interchanged and ‘×’ and ‘+’ are interchanged?
15 × 9 + 7 ÷ 26 – 13 = ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 76.
Given equation: 15 × 9 + 7 ÷ 26 – 13 = ?
if ‘÷’ and ‘–‘ are interchanged and ‘×’ and ‘+’ are interchanged:
15 + 9 × 7 - 26 ÷ 13 = ?
? = 15 + 9 × 7 - 2
? = 15 + 63 - 2
? = 78 - 2 = 76
