Question

Average age of a and b is 24 years and average age of b c and d is 22 years what the sum of the a b c d

Answer 1

Step-by-step explanation:

Average = (sum of the observations) /

(number of observations)

Given,

avg age of a&b is 24 yr's

Let age of a is 'a' and age of b is 'b'

avg=(a+b)/2

24 =(a+b)/2

a+b=24*2

a+b=48 let this be eq1

Given,

avg age of b, c, d is 22 yr's

Let age of c is 'c' and age of d is 'd'

avg=(b+c+d)/3

22 =(b+c+d)/3

b+c+d=22*3

b+c+d=66 let this be eq2

By adding eq1 and eq2 we get

a+b+b+c+d=48+66

a+2b+c+d=114

so here data is inadequate we can't find a+b+c+d with the given data.
