Notez numerele cu a si b
a - b = 81 919 → diferenta
a : b = 27 rest 1 657 ⇒ a = 27 × b + 1 657
27 b + 1 657 - b = 81 919
26 b = 81 919 - 1 657
26 b = 80 262
b = 80 262 : 26
b = 3 087 → al doilea numar
a = 3 087 + 81 919 = 85 006 → primul numar
Media aritmetica= ( 85 006 + 3 087 ) / 2 = 88 093 / 2 = 44 046, 5
a-b=81919, a/b=cat27rest1657, a=27b+1657 (teorema impartirii cu rest)
27b+1657-b=81919, 26b=81919-1657=80262, b=80262/26=3087
a=81919+3087=85006
media aritmetica=(85006+3087)/2=88093/2=44046,5
