Let

f(x) = {x}^{3}  - 5 {x}^{2}  - px + 24

g(x) = x - 4

So

Now it is given that

{x}^{3}  - 5 {x}^{2}  - px + 24 = (x - 4) \: q(x)

So (x - 4) is a factor of {x}^{3}  - 5 {x}^{2}  - px + 24

So Remainder = 0

Now for the zero of polynomial g(x) we have

g(x) = 0

 \implies \: x - 4 = 0

 \implies \: x \:  = 4

So By the Remainder Theorem the Remainder is

 = f(4)

= {4}^{3}  - 5 \times  {4}^{2}  - p \times 4 + 24

 = 64 - 80 - 4p + 24

 = 8 - 4p

By the given condition

8 - 4p = 0

 \implies \: 4p = 8

 \therefore \: p \:  = 2
