Answer 2

Given:

• The ages of Radha and Raghu are in the ratio 5:7.
• Four years from now the ratio of their ages will be 3:4

To Find:

• Their Present Ages?

Solution:

Let the ages will be:

• Radha age= 5x
• Raghu age= 4x

After 4 years:

• Age of Radha=5x+4
• Age of Raghu=7x+4

$\\\\{\color{green}{\bigstar}}{ \: \underline{\sf{ \pmb{According \: to \: the \: Question }}} }$

$\begin{gathered} : \implies\sf{\dfrac{5x+4}{7x+4}=\dfrac{3}{4}} \\ \\ \\ : \implies\sf{4(5x+4)=3(7x+4)} \\ \\ \\ : \implies\sf{20x+16=21x+12} \\ \\ \\ : \implies\sf{20x-21x=12-16} \\ \\ \\ : \implies\sf{-x=-4} \\ \\ \\: \implies\sf { {\cancel-}x= {\cancel-}4} \\ \\ \\ : \implies \underline{\boxed{\frak{x=4}}} \pink\bigstar \\ \\ \\ \end{gathered}$

Therefore,

$\begin{gathered}\longmapsto\sf{Present\:Age\:of\:Radha=5(4) = \textsf{ \textbf{20\:yrs}}} \\ \longmapsto\sf{Present\:Age\:of\:Raghu=7(4) = } \textsf{\textbf {28\:yrs}}\end{gathered}$

$\\\underline{\sf{ \color {navy}\: Hence, the \: Radha \: and \: Raghu \: ages \: are \textsf{ \textbf{20}} \: and \textsf{ \textbf{28}} \: years \: respectively}}.$
