Question

average of five number is hundred if one no. is increased by 5 find new average​

Answer 1

Answer:

101

Step-by-step explanation:

let sum of all numbers is :x

then ,

x/5 =100

x=100×5

x= 500

now , add 5 to x

x'= x+5

x' =500+5

x' = 505

average = x'/5

= 505/5 = 101

Answer 2

a+b+c+d+e /5 = 100

Now if one no. is increased by 5 ...

(a+5)+b+c+d+e /5

= 5/5 + a+b+c+d+e /5

= 1 + 100

= 101..........
