Answer 1

Answer:8

Step-by-step explanation:

X is 14th from front

Y is 17th from end

There are 48 in total

Now let us find how many are there between x and y

48-(14+17)= 17

We know that z is exactly between x and y

Other than z there are 16 btw xand y

That is 8 between x and z and 8 btw z and y ( z is 9th among 17)

So answer is 8.
