Solution :
Explanation Option [b] is correct. Let the age of Arvind and his father be x and 4x years, respectively. Five years ago/the age of Arvind was (x ? 5) years and that of his father was (4x ? 5) years. Now, according to the information given in the question, or \[\left( 4x-5 \right)=7\left( x-5 \right)\] or \[4x-5=7x-35\] \[3x=30\] or \[x=10\]years Therefore, the age of Arvind and his father are 10 years and 40 years, respectively.
