If A denotes ‘+’, B denotes ‘×’, C denotes ‘−’ and D denotes ‘÷’, then what will come in place of ‘?’ in the following equation?
17 A (31 B 3) C (64 D 8) A 41 C (21 B 4) =?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 59.
Given the equation: 17 A (31 B 3) C (64 D 8) A 41 C (21 B 4) =?
After interchanging the expression becomes:
= 17 + (31 × 3) - (64 ÷ 8) + 41 - (21 × 4)
= 17 + 93 - 8 + 41 - 84 = 59
