3 votes 3 votes Answer: (c) x% of y = x/100*y= xy/100 y% of x =y/100*x = xy/100 => xy/100+xy/100 = (2/100)*xy= 2% of xy amanverma== answered Dec 28, 2018 amanverma== comment Share Follow See all 0 reply Please log in or register to add a comment.
1 votes 1 votes Observe that [(X%of Y) = (Y%of X) .] Therefore,(X% of Y)+(Y% of X)=2*(X% of Y)=2*(Y% of X)=2*(X*Y*1/100)=(2/100)*(X*Y)=2%of(XY). sayan chowdhury answered Dec 17, 2021 sayan chowdhury comment Share Follow See 1 comment See all 1 1 comment reply raja11sep commented Dec 21, 2021 reply Follow Share Nice 1 votes 1 votes Please log in or register to add a comment.
0 votes 0 votes $(x\% y)+(y\%x)$ $\Rightarrow (\frac{x}{100})*y+(\frac{y}{100})*x$ $\Rightarrow \frac{x*y}{100}+\frac{y*x}{100}$ $\Rightarrow \frac{2xy}{100}\equiv 2\%\text{xy}$ Option $(C)$ is correct.
