There are two easy ways for solving this problem.
1. x = 5% of y and x = 10% z
5%y = 10%z
y = 2z
x*100/(y+z) = 0.1z*100/(2z+z) = 0.1*100/3 = 10/3
2. We need to be aware of picking numbers for y or z.
if we chose 100 for y then it will be 50 for z and 5 for x
x*100(y+z) = 5*100/(100+50) = 500/150 = 10/3
1. x = 5% of y and x = 10% z
5%y = 10%z
y = 2z
x*100/(y+z) = 0.1z*100/(2z+z) = 0.1*100/3 = 10/3
2. We need to be aware of picking numbers for y or z.
if we chose 100 for y then it will be 50 for z and 5 for x
x*100(y+z) = 5*100/(100+50) = 500/150 = 10/3
