Initially Kevin had 25

Step-by-step explanation:

Given that,

James have 20 more than Kevin

J = K + 20

If Kevin loose 10 then james will have 3 time Kevin

J = 3( K - 10)

Equate both the equation,

3(K-10) = K+20

3k - 30 = k +20

3k - k = 20 + 30

2k = 50

K = 25

So initially Kevin had 25

stops on an even number.
