let my age = x
father's age = 32 + x
grandmother's age = 4x + 10
sister's age = x - 4
friend's age = x + 5
mother's age = x×2
mother's friend's age = 3 × mother's age = 77
mother's age = 77 ÷ 3 = 25.6 years
my age = 25.6 ÷ 2 = 12.8 years
father's age = 32 + 12.8 = 44.8 years
grandmother's age = 4 × 12.8 + 10 = 61.2 years
sister's age = 12.8 - 4 = 8.8 years
friend's age = 12.8 + 5 = 17.8 years
