Answer 1

$\textbf {Hey there, here is the solution.}$

.............................................................................................

Let the daughter be x years old

mother = 3x

Father = 3x + 5

Given that daughter is 10 years old

Father = 3(
10) + 5 = 35 years old

The daughter was born 10 years ago,

Father = 35 - 10 = 25 years old

Answer 2

Hey
______

$\textbf{Solution:}$

Let the age of daughter be $\bold{x}$ years.

Now,

Age of Mother = $\bold{3x \: or \: 3 \times x \: (thrice)}$

Age of Father = $3\underline{\bold{x}}+ 5$

Let $\underline{\bold{x}} = 10$

= > $\bold{(3 \times 10 )+ 5 = 35}$

$\underline{\textit{The \:daughter\: was\: born\:10\: years\: ago...}}$

= > $\bold{35 - 10 = 25 \: years}$

$\textbf{Thus, the age of Father when}$$\textbf{the daughter born is}$ $\bold{25 \: years \: old.}$

$\textbf{Answer:}$ $\large{\fbox{\bold{25 \:years \:old}}}$
