Let their ages before 4 years be a,b respectively.
4 years ago,
a / b = 2/3
a=(2/3)b
4 years later, means a+8,b+8
a+8 / b+8 = 5 / 7
by cross multiplying.
7a + 56 = 5b +40
solving above two equations for a and b, we get
a= 32
b= 48
so their present ages are
a+4 = 36
b+4 = 52
hence
A's present age is 36 yrs
B's present age is 52 yrs
Hope it helped you.
Please let me know if any further doubt.
Cheers !!!
