If ‘+’ means ‘÷’, ‘-’ means ‘+’, ‘×’ means ‘-’ and ‘÷’ means ‘×’, what will be the value of the following expression?

[{(49 × 12) − (6 ÷ 2)} + (4 − 3)] ÷ 5

Show answer & explanation

Correct answer: A

Explanation

The correct answer is Option 1 i.e. 35.

Given equation: [{(49 × 12) − (6 ÷ 2)} + (4 − 3)] ÷ 5

Given directions: ‘+’ means ‘÷’, ‘-’ means ‘+’, ‘×’ means ‘-’ and ‘÷’ means ‘×’

After interchanging the expression becomes:

= [{(49 - 12) + (6 × 2)} ÷ (4 + 3)] × 5

= [{37 + 12} ÷ 7] × 5

= [49 ÷ 7] × 5

= 7 × 5

= 35

Hence, 35 is the correct answer.
