If the average of 3 distinct positive integers is 6, what is the largest possible value of any of them?
a.6
b.16
c.15
d.10
e.18

• the answer is c). 15
  the total of the three distinct positive numbers comes out to be (6*3)=18.
  so the combination involving largest value can be 1,2 & 15

• 15 is correct as they are distict(15+1+2)/3=6
• 11 years agoHelpfull: Yes(7) No(0)
• answer is 15.
  (15+2+1)/3=6
  0 is neither possitive nor negative integer.

• 15
  coz (x+y+z)/3 = 6
  x+y+z = 18
  so as given x,y,z are distinct the largest num must be less than 18
  so if 16 the other two wud be 1,1 but not distict so 15+2+1 are 3 distinct

• answer:15(c)
  We are going to use the formula for the average of three numbers and work backwards to find the answer to your question.
  
  We find the average of three distinct integers by finding their sum and dividing by three.
  
  Since we divide the sum by 3 and get 6 as the average, the sum of the integers must be 18. (18/3 = 6.)
  Now we have three distinct integers that add up to 18. We want to know what is the greatest possible value for one of them. If one integer is going to be as large as possible, the other two must be a small as possible. The two smallest positive integers are 1 and 2.
  Now we have 1 + 2 + [our mystery integer] = 18.
  1 + 2 = 3, so our mystery integer must be 15. (15 + 3 = 18.)

• i think ans is 16 option b
  (x+y+z)/3=6
  x+y+z=18
  by trail and error method (16+1+1)/3=18

• 15
  since 15+1+2/3=6

• let a,b,c be three distinct +ve numbers so as to get the max possible value of a,b,c such that they give an avg of 6
  two of them must be smallest
  so 1,2 therefore the largest number we can obtain is 15
• 11 years agoHelpfull: Yes(2) No(0)
• answer is 16.
  the three integers are distinct so (0+2+16)/3=6
• 11 years agoHelpfull: Yes(1) No(7)
• @SANDY its 3 different.........
• 11 years agoHelpfull: Yes(1) No(0)
• (1+2+x)/3 = 6 , => x = 18 - 3 = 15
  
  Answer = 15
• 11 years agoHelpfull: Yes(1) No(0)
• THEY AS LARGEST VALUE..... 15 IS NOT
  16+1+1=18/3
  SO ANS IS 16
• 11 years agoHelpfull: Yes(1) No(1)
• distinct means different.so 1,2,15 are the numbers whose avg is 18. so 15 is the largest value
• 11 years agoHelpfull: Yes(0) No(0)
• I think 15 because,the total of the three distinct positive numbers comes out to be (6*3)=18.
  so the combination involving largest value can be 1,2 & 15
• 11 years agoHelpfull: Yes(0) No(0)
• (c) 15 as smallest possible distinct positive no. are 1 and 2. and average of 3 nos is 6 i.e their sum is 18. so 18-3=15
