Question 968559
s = the son's age
f = father's age
g = grandfather's age
:
write an equation for each statement. Arrange equations to be in terms of f
:
 Baichung's father is 26 years younger than Baichung's grandfather
g = f + 26
 and 29 years more than Baichung.
s = f - 29
 The sum of all the three ages is 135.
s + f + g = 135
Replace g with (f+26) and replace s with (f-29)
(f-29) + f + (f+26)
3f - 3 = 135
3f = 138
f = 138/3
f = 46 yrs is father's age
then
46 + 26 = 72 yrs is grandfather's age
and
46 - 29 = 17 yrs is son's age
:
:
Confirm this, see if it all adds up
17 + 46 + 72 = 135
 What is the age of each one of them?
