Question

the mean of a b c d and e is 28 if the mean of A,C and e is 24 find the mean of B and d

Answer 1

Answer:

The mean of b and d =  29

Step-by-step explanation:

It is given that

The mean of a b c d and e is 28 and

the mean of A,C and e is 24

To find total sum

If a,b,c,d,and e are 5 numbers

The sum of this five numbers = 5 x 28 =140

To find sum of a,c,e

The mean of a,c e is 24. which means that

sum of a,c, and e is 24 x 3 = 72

To find mean of b and d

Then sum of b and d = 140 -72 = 58

Therefore the mean of b and d = 58/2 = 29
