In a market 4 men are standing. The average age of the four before 4years is 45, after some days one man is added and his age is 49. What is the average age of all?

• suppose total age of four ppal = x
  so before 4 years , the total was x-16
  so that the avg (before 4 yrs) = (x-16)/4 =45.. x=196
  now after some days 49yrs is being added.
  So avg is , (x+49)/5 = (196+49)/5 = 49

• The average age of the four before 4years is 45.
  The average age of the four men now is 45+4=49 years.
  one man is added and his age is 49.
  the average age of all will remain same i.e. 49 as age of new man = av. age of 4 men.

• The average age of the four before 4years is 45.
  The average age of the four men now is 45+4=49 years.
  
  p1+p2+p3+p4/4=49
  
  p1+p2+p3+p4=196
  
  after one joined 196+49=245
  
  so now 254/5=49
  
  so answer is 49
  
  since 5th person also at the age of 49 average remains same.

• * answer 49
  * let us assume those 4 memebers age is a,b,c, and d respectively.
  * 4 years before their respective age is a-4, b-4,c-4,and d-4.
  * but, in that time the average of 4 memebers age is (a+b+c+d-16)/4 = 45.
  * now,we can get the average age of present year.
  i.e (a+b+c+d)/4 = 49.
  now add one person with age 49.
  * so, average age of 5 members is 49.

• 4 year ago the age=4*45
  so after 4 year(today) the 4 man age=4*45+4*4=196
  5th man age=49
  so total of 5 man avg=(196+49)/5=245/5=49

• TOTAL AGE=Z
  B4 4 YEARS,TOTAL AGE=Z-4*4=Z-16
  B4 4 YEARS AVG=(Z-16)/4=45...SO Z=196
  NOW,Z+49/5=196+49/5=49

  before 4 is 45 i.e now 49,
  49*4(men)=196
  one person added s0, 49(now age of 5 th)*5(men)=245
  then 245-196=49
