Answer:
7 years ago, the ages of A and B were in the ratio 4 : 5
7 years hence, they will be in the ratio 5 : 6.
___________________________
▪To Find :-
Present Ages of A and B.
___________________________
▪Solution :-
Let,
Present Age of A be = x years
Present Age of B be = y years
《 7 years Ago 》
Age of A = (x -7) years
Age of B = (y - 7) years
According to the Given Condition :
\begin{gathered} \sf \dfrac{x - 7}{y - 7} = \dfrac{4}{5} \\ \\ \sf5(x - 7) = 4(y - 7) \\ \\ \sf 5x - 35 = 4y - 28 \\ \\ \large\bf 5x - 4y = 7 \: \: \: \:. \: . \: . \: \{i \}\end{gathered}
y−7
x−7
=
5
4
5(x−7)=4(y−7)
5x−35=4y−28
5x−4y=7...{i}
《 7 years Hence 》
Age of A = (x + 7) years
Age of B = (y + 7) years
According to the Given Condition :
\begin{gathered} \sf \dfrac{x + 7}{y + 7} = \dfrac{5}{6} \\ \\ \sf6(x + 7) = 5(y + 7) \\ \\ \sf6x + 42 = 5y + 35 \\ \\ \large \bf6x - 5y = - 7 \: \: \: \:. \: . \:. \: \{ii \}\end{gathered}
y+7
x+7
=
6
5
6(x+7)=5(y+7)
6x+42=5y+35
6x−5y=−7...{ii}
Solving equations {i} and {ii}
We get,
\begin{gathered}\Large\purple{ \underline {\boxed{{\bf x = 63 \: years} }}} \\ \\ \Large\purple{ \underline {\boxed{{\bf y = 77 \: years} }}}\end{gathered}
x=63years
y=77years
Hence,
• Present Age of A = 63 Years
• Present Age of B = 77 Years
