Answer :

Yes.. some no. may be divisible by 8 which comes in 4's table.. ans some of them not.

Like --- 16 both comes in 8th and as well as.. 4's table

where as.. 28 only comes in 4's table and is not divisible by 8.
Yes, we skip a value in the table of 4, and find it in 8's table. For example,here is the table of 4 : 4 8 12 16 20 24 28 32.. So now let us check if all the numbers match with 8 : 8 16 24 32 40 48... How many match? 8:8, 16:16, 24:24, 32:32, etc... Hope you understood...
