Answer:
Ram's father is 4 times as old as Ram. Five years ago, his father was 9 times as old as he was then. What are their present ages?
Let Ram’s father = x
Let Ram = y
Ram's father is 4 times as old as Ram gives us our first formula:
x = 4y
Five years ago, his father was 9 times as old as he was then gives us our second formula:
(x-5) = 9(y-5)
Now, substitute 4y in for x in the second equation and solve for y:
(4y-5) = 9(y-5)
4y-5 = 9y-9*5
4y-5 = 9y-45
-5+45 = 9y-4y
40 = 5y
y = 40/5 = 8 Ram is 8 years old
Now, use the first equation to get his father’s age
x = 4y
x = 4*8 =32 Ram’s father is 32 years old
