If A denotes ‘+’, B denotes ‘×’, C denotes ‘−’, and D denotes ‘÷’, then what will come in place of ‘?’ in the following equation?
7 A 3 B 24 D 2 = 20 B ? A 3
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 2.
Given conditions: A denotes ‘+’, B denotes ‘×’, C denotes ‘−’, and D denotes ‘÷’
Given equation: 7 A 3 B 24 D 2 = 20 B? A 3
After interchanging the expression becomes:
7 + 3 × 24 ÷ 2 = 20 × 2 + 3
7 + 3 × 12 = 40 + 3
7 + 36 = 43
43 = 43
