10 years ago, my father was 8 times my age at that time, and my grandpa was 21 years more than my father.
The ratio of my present age to my farther's age 10 years ago is 7:16.
What is age of my father + age of my grandpa + my age?
Your age now =A Father's age now =F F - 10 =8*(A - 10) A / (F - 10) =7 / 16, solve for A, F A = 14 years - your age now F = 42 years - Your father's age now.
Grandpa =32 + 21 + 10 =63 years - his age now.
14 + 42 + 63 =119 years - your combined ages !.
