Question

2 no.are respectively 10%and 20%more than a third number ;the percentage that is first of the second is ?​

Answer 1

Answer:91.666%

Step-by-step explanation:

Let the three numbers be x,y and z

By question,

x=z+10% of z=z+(10/100)×z=z+(z/10)=11z/10

And,

y= z+20% of z=z+(z/5)=6z/5

%(xof y)=(x/y)×100%

=[{11z/10}/{6z/5}]×100%

=(11z×5)/(10×6z)×100%

={(11×100)/12}%=91.666%
