The Age Group Average Problem is as follows :

**Question :**

The average age of 10 members of a committee is the same as it was 4 years ago, because an old member has been replaced by a young member. Find out how much younger is that new member ? ** **

**Solution :**

Now to solve this sum, there are many complicated ways But Ill show you the simplest one

We know that since there are 10 members, after 4 yrs each of them gets 4 yrs older. Hence the group combined, has aged 40 yrs. Hence,

If the new member has to keep the average the same as 4 yrs ago, he should be 40 yrs younger than the member he is replacing 😉

Hence the answer is **40 yrs **
