Answer:
x= 5, y= 20
Step-by-step explanation:
x , 10, y ,20
for continuous Proportion
x*n =10 or n= 10/x
10*n= y or 10*10/x = 100/x = y
y*n = 40
put n , y values
100/x*10*x = 40
1000/x^2 = 40
or 1000/40 = x^2
25 = x^2
x = 5
and
x*n = 10
5*n = 10
n = 2
so
5, 5*2, 10*2 , 20*2
5, 10, 20 ,40
x= 5 y = 20
