If x = 0. rstu, where r, s, t, and u each represent a nonzero digit of x, what is the value of x?

(1) r = 3s = 2t = 6u
(2) The product of r and u is equal to the product of s and t




I don't understand what is asked in the question :? . It's an OG(green one) question. Could any smart brains please help?

The question says x = 0.rstu for e.g. 0.1234. With the information given, they are looking for us to find all four digits.

1) each of r, s, t, u are <10 (since they are digits in x)
if r=6u, then u must be 1 => you can find x .........suff

2) Doesnt help, ru=st, can be anything at all, specially since we dont know if rust can all be the same numbers or not........insuff

only u = 1 satisfies the condition of digits. if u=2, r becomes 12 and does not fit. Hence A
