Answer 1

Answer:

The sum of their ages three years ago is 68 years

Step-by-step explanation:

Let present ages of A,B and C be x,y,z.

∴x+y+z=77

Age of A three years ago=x-3

Age of B three years ago=y-3

Age of c three years ago=z-3

Sum of their ages three years ago,

∴x-3+y-3+z-3=77

∴x+y+z-9=77

∴x+y+z=68

The sum of their ages three years ago is 68 years .
