if x=0.rstu, where r,s,t,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 product of s and t == Message from GMAT Club Team == This is not a quality discussion. It has been retired.

statement 1 : r=3s=2t=6u
We know that each of them is a single digit number. The only possible value for u is 1, if we take 2,3.... onwards, r will be 12, 18..... so u = 1, r=6, s=2, t=3
Suff.
Statement 2: ru = st 1*8 = 2*4 1*6 = 2*3
Not Suff.
Answer A.

excellent..i totally forgot that they were digits.. A it is.. r=6u..and since r and u represent nonZERO DIGITs..u can only be 1..r=6.. durgesh79 wrote: statement 1 : r=3s=2t=6u

1) rstu each is single digit so u can not be greater than 1. If u is greater than 1 then the value will become double digit number (12, 18, 24 etc.) which is not possible. so, r = 3s = 2t = 6 x 1 r = 6, s = 2, t = 3 and u = 1 statement 1 is sufficient. 2) ru = st give no information about the value. insufficient. Ans. A

Recognizing that r,s,t,u are single digit numbers...we can safely assume that u equals to 1.....leading to values of all other digits....making statement A sufficient....in case of statement B....many values of r,s,t,u can be found resulting in insufficient data....thus statement A is sufficient for the answer
