First I thought, since the question said S:A is doubled, S:A is 1:25 originally, i doubled both numerator and denominator which is incorrect and got the wrong answer. Since it says the quantity is doubled, only the numerator to be increased for the quantity to be doubled.
Is the interpretation of my mistake correct?
