If M denotes ‘-’, N denotes ‘÷’, O denotes ‘×’ and P denotes ‘+’, then what will come in place of ‘?’ in the following equation?
(38 O 13) N 19 M 27 P (38 O 3) P 43 M 68 = ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 88.
The given equation is: (38 O 13) N 19 M 27 P (38 O 3) P 43 M 68
M denotes ‘-’, N denotes ‘÷’, O denotes ‘×’ and P denotes ‘+’.
Putting the signs, the equation becomes
(38 × 13) ÷ 19 - 27 + (38 × 3) + 43 - 68
By using the BODMAS rule,
(38 × 13) ÷ 19 - 27 + (38 × 3) + 43 - 68
= 494 ÷ 19 - 27 + 114 + 43 - 68
= 26 - 27 + 114 + 43 - 68
= 26 + 114 + 43 - 27 - 68 = 88
