Answer 1

$\textbf{Given:}$

$\textsf{The age of Ankit's father is 7 years more than 3 times}$

$\textsf{Ankit's age.Ankit's father is 64 years old}$

$\textbf{To find:}$

$\textsf{Ankit's age}$

$\textbf{Solution:}$

$\textsf{Let the ages of Ankit and his father be x and y}$

$\mathsf{Then,\;clearly\;x\,<\,y}$

$\textsf{As per given data,}$

$\mathsf{y=3x+7}$

$\mathsf{But\;y=64}$

$\mathsf{But\;y=64}$

$\mathsf{3x+7=64}$

$\mathsf{3x=64-7}$

$\mathsf{3x=57}$

$\implies\boxed{\mathsf{x=19}}$

$\therefore\mathsf{Ankit's\;age\;is\;19\;years}$
