Let the ages of grandmother, her daughter and the grandchild be x, y and z respectively in years.

z in days = y in weeks
z * 365 = y * 52 ... (i)

Similarly, z in days = x in years
z*365 = x ... (ii)

Also, x + y + z = 130 ... (iii)

Substituting the values of x, y and z in equation (iii) we get,

365*z + (365/52)*z + z = 130

Solving this we get z = 0.3485 in years = 127 days

So the child is 127 days old.
