Answer 2

♠ Given :-

• A man is four times as old as his Son.

• After four years the man will be thrice as old as his son.

-------------------------------

♠ To Find :-

• The Present Ages of Both.

-------------------------------

♠ Solution :-

Let Present age of Son be = x years

So, Present age of Man will be = 4x years

$</p><p>\Large \bigstar \: \underline{ \pmb{ \mathfrak{《\text{A}fter \:\:4 \:\text{ Y}ears》 }}}</p><p>$

• Age of Man = (4x + 4) years

• Age of Son = (x + 4) years

$</p><p></p><p>\large \bigstar \: \underline{ \pmb{ \mathfrak{ \text{A}ccording \: to \: the \:Given \: Condition }}}$

$</p><p> </p><p></p><p>\begin{gathered}\sf (4x + 4) = 3(x + 4) \\ \\ \sf4x + 4 = 3x + 12 \\ \\ \sf4x - 3x = 12 - 4 \\ \\ \Large \purple{ :\longmapsto \underline {\boxed{{\bf x = 8\: years} }}} \end{gathered} </p><p>$

$\large \bigstar \: \underline{ \pmb{ \pmb{So \: ,}}}$

$</p><p></p><p></p><p>\begin{gathered}\sf4x = 4\times 8 \\ \\ \Large \purple{ :\longmapsto \underline {\boxed{{\bf 4x = 32 \: years} }}}\end{gathered} </p><p></p><p> </p><p> </p><p>$

$\large \bigstar \: \underline{ \pmb{ \mathfrak{H}ence }}$

• Present age of Man = 32 years

• Present age of Son = 8 years.
