If ‘N’ means ‘×’, ‘T’ means ‘–’, ‘M’ means ‘÷’, ‘A’ means ‘=’, and ‘R’ means ‘+’, then which of the following equations will be logically correct?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 36M18N36R18T36A54.
Given conditions:
‘N’ means ‘×’
‘T’ means ‘–’
‘M’ means ‘÷’
‘A’ means ‘=’
‘R’ means ‘+’
Option 1: 36M18N36R18T36A58
After interchanging the expression becomes:
= 36 ÷ 18 × 36 + 18 - 36 = 58
= 54 is not equal to 58.
Option 2: 36M18N36R18T36A54
After interchanging the expression becomes:
= 36 ÷ 18 × 36 + 18 - 36 = 54
= 54 is equal to 54.
As we have found our answer, so, there is no need of checking other options.
Hence, option 2 is the correct answer.
