5,10,17,23,x. St. 1 x is the median; so x=10 or 10<x<17 hence insufficient St. 2 Let mean = y; x=y3 Mean= (55+x)/5 =y 55+x=5y 55+y3=5y y=13 Hence x=10 Finite answer Sufficient. Answer B

(1) x is the median of the set
(2) x is 3 less than the mean of the set Arranging terms in increasing order {5, 10, 17, 23, x} Statement (1): x is the median of the seti.e. {5, 10, x, 17, 23} but according to this condition x may be anything from 10 to 17 inclusive hence x may be equal to 10 or greater than 10 NOT SUFFICIENT Statement (2): x is 3 less than the mean of the seti.e. x+3 = (55+x)/4 We get exact value of x hence SUFFICIENT Answer: Option B

It is B A says that x is median so X can be 10, 11 12 or anything so not sufficient however B says that 5+10+17+23+x/5 = x3solving this we get the value of x which is 12 thus x > 10

(1) x is the median of the set
(2) x is 3 less than the mean of the set Statement 1 actually x could be exactly 10. insuff Statement 2 x3 = 55 +x /5 15x 15= 55 + x 15x = 70 +x 14x= 70 x=5 Suff B

10,17,5,23,x In the set of data above, is x>10? (1) x is the median of the set (2) x is 3 less than the mean of the set Bunuel Could you explain, where I am getting wrong. My choice is D. Both should suffice. 1) x is the median. Median No means Middle No of a set of numbers. Arranging the nos, we get : 5, 10, 17, 23 (x5) + (x10) = (17x) + (23x) => 2x15 = 402x => 4x=55 => x=13.75≈14. Thus x>10 2) x = ((5+10+17+23+x)/5)  3. From this we can deduce the value of x

There are few errors in above post except for the one. 10,17,5,23,x In the set of data above, is x>10? (1) x is the median of the set Statement 1 says only the median. Arranging in asecending order we have, 5,10,x,17,23 ( Since x is the median , so kept in the middle) : Now x could be either 10 or more than 10 but less than equal 17( So mathematically, 10<=x<=17) . Not sufficient (2) x is 3 less than the mean of the set Statement 2 :Now we know that mean = (5+10+17+23+x)/5 = (55+x)/5 = 11+x/5 Now this expression(which is Mean) is equal to 3 more than x Hence we have the equation as : x+3 = 11+x/5 A simple linear equation for which x has a unique value. Hence SUFFICIENT The answer should be B Hope that helps!

Statement 1: X can b 10 or 11. Not sufficient. Statement 2: 55+ m3 = 5m So m is 13 and X is 10. Thus, X has a unique value of 10 and the answer is NO. X is 10 , not bigger than 10
