Why my code is wrong for given question?

Python3.6

There are N problems in this contest; each problem has a unique problem code between 1 and N inclusive. Appy and Chef decided to split the problems to solve between them ― Appy should solve the problems whose problem codes are divisible by A but not divisible by B, and Chef should solve the problems whose problem codes are divisible by B but not divisible by A (they decided to not solve the problems whose codes are divisible by both A and B).

To win, it is necessary to solve at least K problems. You have to tell Appy whether they are going to win or lose.
1≤T≤15
1≤K≤N≤106
1≤A,B≤103

For each test case, print a single line containing the string "Win" if they can solve at least K problems or "Lose" otherwise (without quotes).

What I have tried:

t= int(input())
for _ in range(t):
    n , a , b , k = input().split()
    p = int(a)*int(b)
    if p<=int(n):
        m = p 
        
    elif p>int(n):
        m = int(n) 
        
    arr_a = []
    i = 1
    while int(a)*i<m :
        arr_a.append(int(a)*i)
        i+=1 
    
    arr_b = []
    i=1
    while int(b)*i<m :
        arr_b.append(int(b)*i)
        i+=1 
    
    if sum(arr_a)>=int(k) and sum(arr_b)>=int(k):
        print("Win")
    else:
        print("Lose")

this code is running only for the sample input but not running for any other input and showing the wrong answer as an error when I'm submitting it in codechef
