What will come in place of the question mark (?) in the following equation, if ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged?
310 × 2 − 3 ÷ 40 + 170 = ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 26.
Given equation: 310 × 2 − 3 ÷ 40 + 170 = ?
On interchanging the signs:
310 ÷ 2 + 3 × 40 - 170 = ?
? = 155 + 120 - 170
? = 275 - 170 = 105
