Question

If the mean of A,b,c,d,e is 28 and the mean of a,c,e is 24 .Then mean of b and d

Answer 1

Step-by-step explanation:

we have,

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

a+b c+d+e = 28×5

a+b+c+d+e = 140.......1

since, (a+c+e)/3 = 24

a+c+e = 24×3

= 72

from eq 1

a+b+c+d+e =140

( a+c+e) +b +d =140

72 +(b+d) =140

b+d = 140-72

= 68

now mean of b and d is

(b+d)/2 = 68/2

= 34.
