After 5 years my father would be half the age of my grandfather and my
grandfather would be twice the age of mine.
Find my grandfathers age after 13 years?
:
f + 5 = (g+5)
2(f+5) = g + 5
2f + 10 = g + 5
2f + 10 - 5 = g
g = 2f + 5, grandpa's age now
In 13 yrs
g = 2f + 5 + 13
g = 2f + 18, that's all we do with the given information
:
"my grandfather would be twice the age of mine."does not make sense
