Question

five whole numbers are written in order

Answer 1

Answer:

$mean \: of \: the \: following \: no.s \: are \: \frac{4 + 6 + x + y + 10}{5} = \frac{20 + x + y}{5} \\ median \: of \: the \: following \: no.s = x \\ \: \: \: \: \frac{20 + x + y}{5} = x \\ = > x + y + 20 = 5x \\ = > 4x - y = 20$

Answer 2

Answer:

x=7, y=8

Step-by-step explanation:

Mean of numbers are (4+ 6 + x + y + 10)/5 = z

Median of the numbers using only the middle 3 numbers.

(6+x+y)/3 = z

since Mean and Median are the same - I've used z for it

Simplifying mean, I get (x+y+20)/5 = z

x+y = 5z-20----a

Simplifying Median, I get (x+y+6)/3 = z

x+y = 3z - 6 ------b

5z-20 = 3z-6

2z =14

z=7

substituting in mean or equation a

x+y=5*7 - 20 = 15

15- can be formed of 7 and 8

substitute in equations to verify the answer.

hence x = 7 and y =8
