Score for sub populations not adding up / not tallying / not matching

Hi,I have a scenario like this - 100 people with say an average score of 53. Let’s say I slice this 100 people to find out the number of managers and their score, I get 10 managers with an average score of 58 and the non managers are 90 with an average score of 53.The averages of 53 and 58 is 55.5 ( rounded off to 56 ) Now the difference is a delta of 3 between the full population & the average of the subpopulations ( 53 vs 56 ). The above scenario is something I see when I analyze the recent engagement survey. Could some one explain why the average scores of the sub populations do not match the average score of the full population ?
