Let the age of B be x.
so,
the age of a = 5 + x
the age of b = x
the age of c = x/2
the age of d = 8+2x
If, d=48 years then, 48=8+2x =>2x=40 => x=20 years

The present population of A = (20 + 5) years = 25 years
The present population of B = 20 years
The present population of C = (20/2) years = 10 years.

Answer

Let the age of B be x.

Let the age of B be x.So,

Let the age of B be x.So,the age of a = 5 + x

Let the age of B be x.So,the age of a = 5 + xthe age of b = x the age of c = x/2

Let the age of B be x.So,the age of a = 5 + xthe age of b = x the age of c = x/2the age of d = 8+2x

Let the age of B be x.So,the age of a = 5 + xthe age of b = x the age of c = x/2the age of d = 8+2xIf, d=48 years then, 48-8+2x =>2x=40 => x=20 years

Let the age of B be x.So,the age of a = 5 + xthe age of b = x the age of c = x/2the age of d = 8+2xIf, d=48 years then, 48-8+2x =>2x=40 => x=20 yearsThe present population of A = (20 + 5)

Let the age of B be x.So,the age of a = 5 + xthe age of b = x the age of c = x/2the age of d = 8+2xIf, d=48 years then, 48-8+2x =>2x=40 => x=20 yearsThe present population of A = (20 + 5)years = 25 years The present population of B = 20 years The present population of C = (20/2)
