What will come in the place of the question mark (?) in the following equation if '+' and '-' are interchanged and '×' and '÷' are interchanged?
11 ÷ 42 × 3 - 69 + 25 = ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 198.
Given equation: 11 ÷ 42 × 3 - 69 + 25 = ?
On changing the signs:
11 × (42 ÷ 3) + 69 - 25 = ?
? = (11 × 14) + 69 - 25
? = 154 + 69 - 25
? = 223 - 25 = 198
