Question

The mean of a,b,c,d,e is 28.Iftje mean of a,c,and e is 24 then mean of b and d is

Answer 1

Answer:

34

Step-by-step explanation:

a + b + c + d + e / 5 = 28

Therefore, a + b + c + d + e = 28x5 =  140

a + c + e / 3 = 24

Therefore, a + c + e = 24x3 = 72

b + d = 140 - 72 = 68

Mean of b and d = b + d / 2

                            = 68 / 2

                            = 34

Therefore, the mean of b and d is 34
