Answer 2

$\huge\bf{Answer :}$

The Numbers are $\huge{12}$ and $\huge{28}$

Step - By - Step Explanation :

Let,

The Two Numbers Be $3x \:</em></strong><strong><em> </em></strong><strong><em>:</em></strong><strong><em> \: 7x$

From Condition :

(Four is Added to Both 3 and 7 Separately)

$\frac{3x + 4}{7x + 4} = \frac{1}{2}$

Hence,

$\frac{3x + 4}{7x + 4} = \frac{1}{2} \: \: \: \: \: \: \: \: \: \: \\ 2(3x + 4) = 1(7x + 4) \\ 6x + 8 = 7x + 4 \\ 7x - 6x = 8 - 4 \: \: \: \: \: \\ x = 4$

Hence,

$3x = 3 \times 4 = 12 \\ 7x = 7 \times 4 = 28$

Therefore,

The Numbers are $\huge{12}$ and $\huge{28}$
