Question

If x and y are inversely proportional, find values of a,b,c in the following.........x/y 90/a b/20 100/27 54/c

Answer 1

Given that. x and y are inverse proportion,

i.e. x∝  

y

1

​  

 

∴xy=K, where K is constant proportionality

Given.  

x=3,y=2

∴3×2=K=6

Answer is 6

Answer 2

Symbol “∝” stands for 'is proportional to'. When two quantities x and y are in inverse proportion (or vary inversely) they are written
