Use formula

$f_{out} = \frac {f_{in}}{mod – n}$

where,

$f_{out} = $ Output frequency

$f_{in} \ = $  Input frequency

$mod – n = $ Modulus of counter

$f_{out} = \frac {2000}{25 * 8} = 10  \ \mathcal Hz$

Note : 4-bit parallel counter === 4-bit synchronous counter

@Yaman Sahu That means

(i) n bit ring counter = %n counter

(ii) n bit Johnson counter = %2n counter

(iii) n bit parallel counter = n bit synchronous counter = n bit asynchronous counter = n bit ripple counter    =  %$2^n$ counter

Is this correct?
