What will come in the place of '?' in the following equation, if '+' and '-' are interchanged and '×' and '÷' are interchanged?
14 + 6 × 3 ÷ 7 - 2 =?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 2.
Given conditions: '+' and '-' are interchanged and '×' and '÷' are interchanged
Given equation: 14 + 6 × 3 ÷ 7 - 2 =?
After interchanging the expression becomes:
= 14 - 6 ÷ 3 × 7 + 2
= 14 - 2 × 7 + 2
= 14 - 14 + 2
= 16 - 14
= 2
Hence, 2 is the correct answer.
