Question : Directions: If A denotes ‘+’, B denotes ‘×’, C denotes ‘−’, and D denotes ‘÷’, then what will come in place of ‘?’ in the following equation?
145 A 27 D 3 B ? = 163
Option 1: 1
Option 2: 2
Option 3: 3
Option 4: 6
Correct Answer: 2
Solution : Given: A denotes ‘+’, B denotes ‘×’, C denotes ‘−’, and D denotes ‘÷’, 145 A 27 D 3 B ? = 163
Replacing the letters with the given mathematical operations. 145 + 27 ÷ 3 × ? = 163 9 × ? = 163 – 145 9 × ? = 18 ? = 2
So, the equation equals to 2. Hence, the second option is correct.
