If ‘A’ denotes ‘+’, ‘B’ denotes ‘×’, ‘C’ denotes ‘–’ and ‘D’ denotes ‘÷’, then what will come in place of ‘?’ in the following equation?
(91 D 13) B 8 C 50 A 16 B 2 A (99 D 11) =?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 47.
Given equation: (91 D 13) B 8 C 50 A 16 B 2 A (99 D 11) =?
After interchanging the expression becomes:
= (91 ÷ 13) × 8 - 50 + 16 × 2 + (99 ÷ 11)
= 7 × 8 - 50 + 16 × 2 + 9
= 56 - 50 + 32 + 9
= 6 + 32 + 9 = 47
