Question

Who am I?
Add twice of me to a dozen and you can get five times a dozen.

Answer 1

Let it be x

2x + 1 dozen = 5 × donzen

⇒ 2x + 12 = 5 × 12

⇒ 2x + 12 = 60

⇒ 2x = 60 - 12

 

⇒ 2x = 48

⇒ x = 48 ÷ 2

⇒ x = 24

Hence

It is number 24

Answer 2

$\textsf{\large{Answer :}}$

$\textsf{\large{24}}$

$\textsf{\large{Explaination}}$

$\textsf{Consider the number as x}$

$\texttt{So, the equation}$

$= > 2x + dozen \: = \: 5 \times dozen$

$= > 2x + 12 = 5 \times 12$

$= > 2x + 12 = 60$

$= > 2x = 60 - 12$

$= > 2x = 48$

$= > x = \frac{48}{2}$


$= > x = 24$

$\textsf{\large{Verification}}$

$= > 2x + dozen \: = \: 5 \times dozen$

$= > 2(24)+ 12 \: = \: 5 \times 12$

$= > 48 + 12 = 60$

$= > 60 = 60$

$\therefore$$\textsf{LHS = RHS}$

$\therefore$$\textsf{The number is 24}$
