What will come in place of the question mark (?) in the following equation if ‘+’ and ‘×’ are interchanged and ‘−’ and ‘÷’ are interchanged?
5 + 3 × 2 ÷ 10 − 5 = ?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 15.
Given equation: 5 + 3 × 2 ÷ 10 − 5 = ?
When +’ and ‘×’ are interchanged and ‘−’ and ‘÷’ are interchanged, then
⇒ 5 × 3 + 2 - 10 ÷ 5 = ?
⇒ 15 + 2 - 2 = ?
⇒ 17 - 2 = 15
