if avaerage of five student ages is 14. what will the average age of these student after 5 years?

• (a+b+c+d+e+f)/5=14
  a+b+c+d+e+f=70------>1
  (a+5+b+5+c+5+d+5+e+5+f+5)/5
  (a+b+c+d+e+f+25)/5 substitute equation 1
  (70+25)/5
  ans=19

• Total age = 14* 5 = 70
  age of 5 student after 5 yrs = 70 + (5*5) = 95
  Avg = 95/ 5 = 19

• it will be 14+5=19 .Because in every year their age is increase by one...

• 15
  
  5 students avg=14
  
  sum =14*5=70
  after 5 years sum=75
  avg=75/5=15

• 19.
  first total sum of ages=14*5=70
  next total age after 5 years be 70+25=95
  average of 5 students be 95/5=19

• a+b+c+d+e=14*5=70
  again ,after five yr average age=a+b+c+d+e+25/5=70+25/5=19

• 5*5=25...25/5=5...i.e 5 students 5 years avg becomes simply '5' so 14+5=19.

• X5/5=14
  x5+5(5)/5
  14+5
  19
• 9 years agoHelpfull: Yes(0) No(0)
• 19 because x5/5=14, we get x5=70 after 5 years we get x5+25/5 =19
  
• 9 years agoHelpfull: Yes(0) No(0)
• let the sum of 5 students is x
  then x/5=14
  x=70
  after 5 years the sum will be x+25(5*5)
  then avg=x+25/5
  avg=95

• a+b+c+d+e+f/5=14--------(i)
  after 5 years
  a+5+b+5+c+5+d+5+e+5/5=unknown
  a+b+c+d+e+f+25/5=unknown
  a+b+c+d+e+f/5+25/5=unknown
  14+5=19=unknown

• after 5 yrs also it is 14 only

• avg =sum of terms/no of terms;sum =?,no of terms=5;avg=14;
  sum of terms=a+b+c+d+e;
  a+b+c+d+e/5=14;a+b+c+d+e=70;
  after 5yrs;-
  a+5+b+5+c+5+d+5+e+5=70;
  a+b+c+d+e=45;
  avg of five students after 5 yrs is 45/5=9
• 8 years agoHelpfull: Yes(0) No(7)
• Avg of 5 students = 14
  In 5 years age of each student would be increased by 5 years
  So, average would also be increased by 5.

• 19(a+b+c+d+e+f)/5=14
  a+b+c+d+e+f=70------>1
  (a+5+b+5+c+5+d+5+e+5+f+5)/5
  (a+b+c+d+e+f+25)/5 substitute equation 1
  (70+25)/5

• 39
  correct ans 19
  if a perticular no is added or substracted from each no then this no will added or substracted from average value
