If ‘+’ means ‘divided by’, ‘ ̶ ’ means ‘added to’, ‘×’ means ‘subtracted from’, and ‘÷’ means ‘multiplied by’, then what will be the value of the following expression?
[{(25 × 13) - (3 ÷ 3)} + (3 - 4)] ÷ 5
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 15.
Given conditions: ‘+’ means ‘divided by’, ‘ ̶ ’ means ‘added to’, ‘×’ means ‘subtracted from’, and ‘÷’ means ‘multiplied by’
Given equation: [{(25 × 13) - (3 ÷ 3)} + (3 - 4)] ÷ 5
After interchanging the expression becomes:
= [{(25 - 13) + (3 × 3)} ÷ (3 + 4)] × 5
= [{12 + 9} ÷ 7] × 5
= [21 ÷ 7] × 5
= 3 × 5 = 15
