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.
