let age of B be x
then age of A will be x+15
age of B 10 years ago = x-10
ago of A 10 year ago = x+15-10= x+5
now according to question 10 years ago age odlf A was 4 times age of B
so
4(x-10) = x+5
4x-40=x+5
3x=45
x=15
now age of B is 15 years and that of A is 15+15=30years.
then age of A will be x+15
age of B 10 years ago = x-10
ago of A 10 year ago = x+15-10= x+5
now according to question 10 years ago age odlf A was 4 times age of B
