Question

if a is x percent more than b and b is Y percent less than a then the relation between X and Y is​

Answer 1

Step-by-step explanation:

a =b (1+x/100) b=a(1-y/100)

a/b=1+x/100. a/b= 1/(1-y/100)

1+x/100=1/(1-y/100)

( 1+x/100) (1-y/100)=1

(100+x)(100-y)=10000

10000 +100x-100y -xy =10000

100x -100y -xy=0

100/y -100/x=1

1/y -1/x =1/100
