B as a percentage of A is equal to A as a percentage of (A+B). Find B as a percentage of A. Choose one:	A) 62%	B) 73%	C) 41%	D) 71%	E) None of these
Explanation :   According to the question:-   =&gt;B/A=A/(A+B).   As B is a percent of A, let us assume B=Ax.   Then, equation (1) can be re-written as   =&gt;x=11+x.   =&gt;x(1+x)=1.   =&gt;x2+x+1=0.   =&gt;x=−1±5/√2   Thus,   x=−1+5 /√2   =&gt;0.62.   =&gt;62%.   62%nswer : 62%
