If ‘+’ means ‘divided by’, ‘ ̶ ’ means ‘added to’, ‘×’ means ‘subtracted from’, and ‘÷’ means ‘multiplied by’, then what will be the value of the following expression?
[{(23 × 15) - (2 ÷ 2)} + (2 - 4)] ÷ 2
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 4.
Given conditions: ‘+’ means ‘divided by’, ‘ ̶ ’ means ‘added to’, ‘×’ means ‘subtracted from’, and ‘÷’ means ‘multiplied by’
Given equation: [{(23 × 15) - (2 ÷ 2)} + (2 - 4)] ÷ 2
After interchanging the expression becomes:
= [{(23 - 15) + (2 × 2)} ÷ (2 + 4)] × 2
= [{8 + 4} ÷ 6] × 2
= [12 ÷ 6] × 2
= 2 × 2 = 4
