Q. The average of 3 numbers is 135.The largest number is 180 and the difference between the others is 25.the smallest number is:

Option
A)130
B)125
C)120
D)100

• Answer will be 100 ;
  The largest number is 180(first no.)
  
  consider the smallest number is x(second no.)
  
  According to the question
  difference between the others is 25
  so third no. will be 25+x
  
  The average of 3 numbrs is 135
  (180 + x + 25+ x)/3 = 135
  205 + 2x = 405
  2x = 405 - 205
  2x = 200
  x = 100
  so the smallest number is 100

• (180+y+z)/3=135
  y+z=225
  y-z=25
  hence y= 125
  z=100
  smallest number is 100

• Sum of three numbers/3=135
  Sum of three numbers=135*3=405
  Given:LargestNumber=180,Diff between two numbers is 25. let the numbers be x and 25+x. so,
  180+X+25+x=405,205+2X=405,2X=405-205,2X=200,X=100.
  Three numbers are 180,100 and 125.the smallest number is 100.

• 100
  avg of 3 number is =135
  =>summation =3*135=405
  summation of other 2 number=405-180=225
  difference between dem is 25
  =>x+(x+25)=225
  =>x=100

• largest number=180;
  difference between other two number is 25;
  so the numbers are 180,x,x+25;
  smallest number is = x
  given that avg of 3 number is 135;so sum=(135*3)=405
  so solve 180+x+x+25=405
  =>x=100;which is the smallest number

• smallest number is 100.let the 3 no.'s be l,m,s
  l=180,m-s=25=>m=s+25,l+m+s/3=135=>180+25+s+s/3=135=>2s=405-205=>s=100

• x+y+180=135*3
  x+y=225
  x-y=25
  x=100,y=125 ans:D

• since there avg=135,its tot=405, then sub 25 as in question given and sub 180 and we get 300 then divide by2 300/2=150 then sub 25 again=125 get

• Simple!!!
  consider numbers as x,y,z
  (x+y+z)/3=135 ------ (1)
  lets consider x as largest number so x=180 and also given that difference between other two nums(y and z is 25)
  So it can be z-y=25 or y-z=25
  lets take z-y=25, then z=y+25 (so finding y gives us the answer)
  by substituting all of these in (1) we get
  (180+y+y+25)/3=135
  by solving we get y=100 (which is smallest)

• (x+y+z)/3 =135
  let x = 180
  y -z =25
  180+y+z =405
  y+z =225
  y-z =25
  y = 125,z =100
  smallest is z
