Hi Sravan,

By using Lightning Data Services(force:recordData tag), we can achieve this . whenever record is updated from standard detail page, recordUpdated event will be fired automatically in the custom lightning aura component which is placed in same page.

Use below code to identify the update event from standard page. 
Add below code in aura Component - .cmp
<force:recordData aura:id="recordLoader"
                      recordId="{!v.recordId}"
                      layoutType="FULL"
                      targetRecord="{!v._record}"
                      targetFields="{!v.sobjectRecord}"
                      targetError="{!v._error}"
                      recordUpdated="{!c.handleRecordUpdated}"/>

Add below code in Controller.js -

handleRecordUpdated : function(component, event, helper) {
        var eventParams = event.getParams();
        if(eventParams.changeType === "CHANGED") {
            var changedFields = eventParams.changedFields;
            console.log('Fields that are changed: ' + JSON.stringify(changedFields));
            component.find("recordLoader").reloadRecord(); // refresh the whole component.
        }
    }
