Hi Hari,

Please try this code:

vf Page 1:

<apex:page Controller="yaQuestionStudentMinMaxAge" >    
<apex:form >        
<apex:pageBlock title="Student Age">            
<apex:pageBlockSection columns="1">                
Min Age<apex:inputText value="{!minage}"/>                
Max Age<apex:inputText value="{!maxage}"/>                  
</apex:pageBlockSection>            
<apex:pageBlockButtons >                
<apex:commandButton action="{!search}" value="Search"/>            
</apex:pageBlockButtons>                        
</apex:pageBlock>      
</apex:form>
</apex:page>

Vf page 2:
<apex:page controller="yaQuestionStudentMinMaxAge" action="{!search1}">
     <apex:form >
         
        <apex:pageBlock title="Student Age">
             <apex:pageBlockTable value="{!studentObj}" var="c">
                <apex:column value="{!c.Name}"/>
                <apex:column value="{!c.minAge__c}"/>
                <apex:column value="{!c.maxAge__c}"/>            
            </apex:pageBlockTable>     
         </apex:pageBlock>
    </apex:form>
</apex:page>

Apex class:

public class yaQuestionStudentMinMaxAge {    
public string maxage{get;set;}    
public string minage{get;set;}    
public List <Student__c> studentObj {get;set;}            
public PageReference search() {        
PageReference redirectPage = new PageReference('https://wise-impala-estvyo-dev-ed--c.visualforce.com/apex/jb?core.apexpages.request.devconsole=1');  //please put here your second vf page URL     
// system.debug('pageReference::'+redirectPage);                
redirectPage.getParameters().put('minimumage',minage);              
redirectPage.getParameters().put('maximumage',maxage);             r
edirectPage.setRedirect(true);        
return redirectPage;    

}    
public void search1(){          
integer minval = integer.valueof(ApexPages.currentPage().getParameters().get('minimumage'));        
 integer maxval = integer.valueof(ApexPages.currentPage().getParameters().get('maximumage'));        
studentObj = new list<Student__c>();        
studentObj=[select Name, minAge__c,maxAge__c from Student__c where minAge__c>=:minval AND maxAge__c<=:maxval ORDER  BY minAge__c ASC];
// you can sort the data in ascending order by minAge__c or maxAge__c.        
system.debug('studentObj'+studentObj);    
}
}

Hope this will help you.
Thanks
