How many percent more of the stars for the repository of solution No.51424 than No.167053?
solution No. refers to Solution.Id; percentage = DIVIDE(MULTIPLY(SUBTRACT(SUM(Solution.Id = 51424), SUM(Solution.Id = 167053)), 100)), SUM(Solution.Id = 167053);
SELECT CAST(SUM(CASE WHEN T2.Id = 51424 THEN T1.Stars ELSE 0 END) - SUM(CASE WHEN T2.Id = 167053 THEN T1.Stars ELSE 0 END) AS REAL) * 100 / SUM(CASE WHEN T2.Id = 167053 THEN T1.Stars ELSE 0 END) FROM Repo AS T1 INNER JOIN Solution AS T2 ON T1.Id = T2.RepoId
