If A denotes ‘+’, B denotes ‘×’, C denotes ‘−’ and D denotes ‘÷’, then what will come in
place of ‘?’ in the following equation?
(13 B 9) D 3 A (14 D 7) B 6 C 21 A (32 B 2) = ?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 94.
Given the equation: (13 B 9) D 3 A (14 D 7) B 6 C 21 A (32 B 2) = ?
After replacement the equation becomes;
⇒ (13 × 9) ÷ 3 + (14 ÷ 7) × 6 - 21 + (32 × 2)
⇒ 117 ÷ 3 + 2 × 6 - 21 + 64
⇒ 39 + 2 × 6 - 21 + 64 ⇒ 94
