Question

60% of Ryan’s savings is equal to 3/10 of Dean’s savings. If Dean’s savings as a ratio of Ryan’s savings in its simplest form can be expressed as p/q, the p + q is ______

Answer 1

Let Ryan's savings be x and Dean's savingd be y.
Given:-
$60\% \: of \: x \: = \frac{3}{10} y \\ \frac{6}{10} x = \frac{3}{10} y \\ \frac{y}{x} = \frac{6}{10} \times \frac{10}{3} \\ \frac{y}{x} = \frac{2}{1} \\ on \: comparing \: with \: given \: condition \\ \frac{2}{1} = \frac{p}{q} \\ p = 2 \\ q = 1 \\ p + q = 2 + 1 = 3$
