I wish this help you that is unusual - did you do an npm uninstall -g composer-playground (global uninstall) first ? Because I just checked this in Linux 16.04 LTS and it comes up with the right version?
npm uninstall -g composer-playground

npm install -g composer-playground 

npm ls -g --depth==0 |grep playground

Hyperledger Composer Playground Query

I wish this help you as Pronoy says, you can use REST APIs. Alternative is to set up a transaction, that calls a defined query (in queries,qry) - purely for testing and logging messages etc. Eg.
return query('selectPerson', {firstName: 'joe'} )
    .then(function (results) {

       for (var n = 0; n < results.length; n++) {
               var person = results[n];
               console.log('person is ' + (n+1) + ', object is ' +  person);
               console.log('person identifier is ' + person.getIdentifier());

         return personRegistry.get(person.getIdentifier())
         .then(function (personRecord) {
            console.log('object is ' + personRecord); // all good
           console.log('identifier is ' + person.getIdentifier() );

       } // for

  }) //function

may help you . I think there is a problem with your starting a business-network or upgrading a business-network. please ensure that your started network version same as composer-rest-server API version shown on http://localhost:3000/explorer/. If there is an issue then you can do ./stopFabric.sh. and then start your business-network again.
