Assume the total work = 48 units.
Capacity fo J = 48 / 16 = 3 units / day
Capacity of P = 48 / 24 = 2 units / day
Capacity of J, P, H = 48 / 8 = 6 units / day
From the above capacity of H = 6 - 2 - 3 = 1
So H takes 48 / 1 days = 48 days to dig the well

j does 1/16 units per day
p does 1/24 units per day
and they together does 1/16+1/24+1/x=1/8
thus h takes 48 days to complete
