Solution 10%of x=(x/100)×10 20%of y=(y/100)×20 Given that (x/100)×10=(y/100)×20 x/y= 20/10 x/y=2/1 x:y = 2:1 gautam gupta 07-25-2021 09:29 AM

ANSWER IS AS we all know that Proportion is the equality of two ratios. a:b::c:d we can also write as a:b=c:d so here a and d are extremes and b and c are means same concept i used here i.e 10% x=20% y so here a=10,b=x, c=20, d=y so same a d are extremses and b c are means so we can rewritten as 10%y=20%x i.e 1y=2x so they ask x:y ratio so 2:1 i hope it is useful sandeep 04-29-2021 02:29 AM
