What will come in place of the question mark (?) in the following equation if ‘+’ and ‘×’ are interchanged and ‘−’ and ‘÷’ are interchanged?
55 × 16 − 4 ÷ 7 + 3 = ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 38.
Given equation: 55 × 16 − 4 ÷ 7 + 3 = ?
If ‘+’ and ‘×’ are interchanged and ‘−’ and ‘÷’ are interchanged, then
= 55 + 16 ÷ 4 - 7 × 3
= 55 + 4 - 7 × 3
= 55 + 4 - 21
= 59 - 21
= 38
