Solution

The correct option is A 12
Let the required number be x.
Step I: 2x + 5
Step II: 2x + 5 = 29
Solving the equation, we get
2x + 5 = 29
$\Rightarrow$ 2x = 29 – 5 (Transposing 5 to RHS)
$\Rightarrow$ 2x = 24
$\Rightarrow$ x = 12 (Dividing both sides by 2)
$\Rightarrow$ x = 12
Thus the required number is 12.
