What will come in the place of the question mark (?) in the following equation if ‘+’ and ‘-’ are interchanged and ‘×’ and ‘÷’ are interchanged?
13 ÷ 145 × 29 - 69 + 27 = ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 107.
Given equation: 13 ÷ 145 × 29 - 69 + 27 = ?
After interchanging the signs:
13 × (145 ÷ 29) + 69 - 27 = ?
= (13 × 5) + 69 - 27
= 65 + 69 - 27
= 134 - 27
= 107
