Question

B as a % of A is equal to A as a % of (A+B). Find B as a % of A.

Answer 1

Explanation:

→B/A = A/ (A+B)

→Assume, B = Ax (B is some percent of A. So consider that some percent as ‘x’.)

→Ax/A = A/(A+Ax)

→X=1/(1+x)

→X^2+ X -1 = 0

→Solving the above equation, we get 0.62(consider only positive terms),

   So the answer is 62%

Answer 2

Answer:

Solving the above equation, we get 0.62(consider only positive terms),

   So the answer is 62%.
