Question

The mean of 24 numbers is 35 . If 3 is added to each number , what will be the new mean.?​

Answer 1

Answer:

38

Step-by-step explanation:

Let us consider 24 numbers as

x1 + x2 + x3.....x24

So the mean will be

x1 + x2 +.....x24/24 = 35....(j)

When we add 3 to each

x1 + 3 + x2 + 3.......x24 + 3

The mean will be

x1 + 3 + x2 + 3...x24 + 3/24

= x1 + x2...x24 + 24(3) /24

= x1 + x2 ....x24/24 + (24×3/24)

= 35 + (72/24) [using (i)]

= 35 + 3

= 38

Therefore the new mean will be 38.

hope it helps.
