If x and y are unknown positive integers, is the mean of the set {6, 7, 1, 5, x, y} greater than the median of the
set?
(1) x + y = 7 (2) x - y = 3

A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D. EACH statement ALONE is sufficient.
E. Statements (1) and (2) TOGETHER are not sufficient.

i think both options are too be used. mean can be calculated using first option but to calculate median, we need to know value of both x and y, so C ?????

i think this is not the answer bro.... here u are calculating the probability of getting all the faces showing 6 but questions says, there should be all six numbers.... he wants 111,2,3,4,5,6 like pattern

1. The remainders when F(x) is divided by x - 99 and x - 19 are 19 and 99, respectively. What is the remainder when F(x) is divided by (x - 19) (x - 99)?




f(x){x-99} + 19 = f(x){x-19} + 99 or f(x) =-1,,, it means x = 119 since f(x)/x-99 =19. it will be 19 -1/(x-99),, it is possible only when x= 119, or -1/20 = 19... similarly solve the another equations.... now we need remaidner of f(x) by (x-99)(x-19) or -1/(20)(100) or 1999 is the answer.

please tell me the good movies which i should see.... also tell me good serials which i can see in my free time .....regards

chillfactor Says

If its either-or, then it will be zero, as if a number is divisible by 10 then its also divisible by 5

Hemant sir, yeh zero kaise hoega... i think iska answer 369/625 diya tha.. app statement ko modify karlo
