James is  x  years older than alex. alex is  x  years older than kim. james is twice as old as kim. alex is 24. which of the following ages is possible for james?

Answer with explanation:

Let age of Kim = k years

Age of James = 2k years(1)

Age of Alex = (k+x ) years

Age of James =k+x+x=(k+2 x) years(2)

Equating (1) and (2)

2 k= k+2 x

2k-k=2x

k=2 x

And, Alex's age=24

k+x=24(3)

k-2x=0---(4)

Subtracting 4 from 3, we get

3 x=24

Dividing both sides by , 3 we get

x=8

Putting the value of x in equation 4, we get

k=2*8

k=16

So, James Age =2k years

               =2*16

               =32 years

Option A: 32

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

after simplifying it i got: -36.25 as my answer. hope that !
