Hi Devi Chandrika,
   Now i am trying for another trailhead challenge and below is my problem statement and my code and error as well.Kindly suggest me.
The Apex class must be called ContactSearch and be in the public scope
The Apex class must have a public static method called searchForContacts
The method must accept two incoming strings as parameters
The method should then find any contact that has a last name matching the first string, and mailing postal code (API name: MailingPostalCode) matching the second string
The method should finally return a list of Contact records of type List that includes the ID and Name fields

My Code:
public class ContactSearch {
    public static contact[] searchForContacts(string lstName,string mpostalcode)
    {
        contact[] cts = [SELECT FirstName,LastName,ID
                          FROM Contact WHERE LastName=:lstName AND mailingpostalcode=:mpostalcode];
            
            return cts;
        
    }

}

I am getting the below error in trailhead challenge.
There was an unexpected error in your org which is preventing this assessment check from completing: System.DmlException: Insert failed. First exception on row 0; first error: REQUIRED_FIELD_MISSING, Required fields are missing: [Loan_Amount__c]: [Loan_Amount__c]

Kindly suggest me.

Executing the 'insertNewAccount' method failed. Either the method does not exist, is not static, or does not insert the proper account.

            acct.NumberOfEmployees = 100;
        insert acct;
        ID acctID = acct.Id;
// Display this ID in the debug log
System.debug('ID = ' + acctID);
