gorv · Answer

varies inversely means 
x$$Y     \alpha \frac{ 1 }{ x }$$

gorv · Answer

to remove proportionality sign let it is $$y=\frac{ k }{ x}$$

gorv · Answer

now we made a relation in x and y where k is constant
now  first x and y are given from there find k value

gorv · Answer

tell me what u got for k ??

anonymous · Answer

SO Y=K/6

gorv · Answer

after getting k 
we have x=6 
so y will be 
$$y=\frac{ k }{ 6 }$$

gorv · Answer

first calculate k

gorv · Answer

given x= 8 and y=10 put these values and find k

anonymous · Answer

k so 80=k
im sorry i rlly suck at this
