If ‘Z’ stands for ‘÷’, ‘Q’ stands for ‘×’, ‘H’ stands for ‘+’, and ‘E’ stands for ‘–’, what will come in place of the question mark (?) in the following equation?
17 H 23 Q 42 Z 7 E 13 =?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 142.
Given conditions: ‘Z’ stands for ‘÷’, ‘Q’ stands for ‘×’, ‘H’ stands for ‘+’, and ‘E’ stands for ‘–’
Given equation: 17 H 23 Q 42 Z 7 E 13 =?
After interchanging the expression becomes:
= 17 + 23 × 42 ÷ 7 - 13
= 17 + 23 × 6 - 13
= 17 + 138 - 13
= 155 - 13
= 142
Hence, 142 is the correct answer.
