Question

If '+' means 'divided by', '-' means 'add', 'X' means 'minus' and '÷' means 'multiplied by', what will be the value of the following expression: [{(21 × 17) - (3 ÷ 2)} + (3 - 2)] ÷ 2
1. 2
2. 1
3. 3
4. 4

Answer 1

Correct Answer - Option 4 : 4

Given expression : [{(21 × 17) - (3 ÷ 2)} + (3 - 2)] ÷ 2

'+' means 'divided by', '-' means 'add', 'times' means 'minus' and '÷' means 'multiplied by'

Replacing the symbols according to the question, we get

[{(21 - 17) + (3 × 2)} ÷ (3 + 2)] × 2

Applying the BODMAS rule, we get

[{4 + 6} ÷ 5] × 2

= [10 ÷ 5] × 2

= 2 × 2

= 4

Hence, 4 is the correct answer.
