let father's present age=x, arthur's age=y and clark's age=z
x=5z
x+y=100
z+(x-y)=8y
solving above three eqs, x= 88.2353

not sure about the solution...plz check!!!

Let us assume clerk age as = X
then Arthur age will be = 5x (when arthur is as old as his father)
also Haily age will be same =5x
Sum of ther ages = 5x+5x=100
therfore x=10
That is clerk age is 10

Let assume clerk age as = X
then Arthur age will be = 5x
also Haily age will be same =5x

Now Clerk age becomes 8(5x)=40x
Sum of ther ages = 5x+5x=100
therfore x=10
That is clerk age is 10
