If ‘+’ means ‘÷’, ‘ -’ means ‘+’, ‘×’ means ‘-’ and ‘÷’ means ‘×’, what will be the value of the following expression?
[{(38 × 23) - (4 ÷ 3)} + (6 - 3)] ÷ 2
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 6.
Given equation: [{(38 × 23) - (4 ÷ 3)} + (6 - 3)] ÷ 2
After interchanging the expression becomes:
= [{(38 - 23) + (4 × 3)} ÷ (6 + 3)] × 2
= [{15 + 12} ÷ 9] × 2
= [27 ÷ 9] × 2 = 6
