Bheja Fry question

 Question 


The average of 7 consecutive numbers is 20. Which is the largest of these numbers ??




Answer 


Let the number be x.

7 consecutive numbers means   =    x,   x+1,     x+2,      x+3  ,    x+4,     x+5,   x+6


Their average is given which is 20.




==>>  (    x  +     x+1      +       x+2        +       x+3       +      x+4       +       x+5        +     x+6     )   /   7   =    20


==>>    (   7x  +   21  )  =   140



==>>  7x  =   140 -21


==>>   7x   =   119


==>>   x  =   17


Biggest number =   x + 6

== >>   17  +  6


Biggest number  ==    23     !!!
