The Mean of three numbers is 10 more than than the least number and 15 less than the highest. Their median is 5. Find the sum of the three numbers.

• given: x+y+z/3=m
  y=5;
  m=x+10;x=m-10;
  z=m+15
  sub in above give eq u will get m= 10;
  sub in x, y, z =0,5,25=total=30

• numbers are 0 5 25
  so sum is =30

• options are: a) 30 b) 20 c) 5 d) 25
  option itself shows
  30 only the divisible of 3.
  so ans is 30.

• mean of 3 no's x+y+z/3=10
  then x+y+z=30
  sum of 3 no's=30

  options are: a) 30 b) 20 c) 5 d) 25
  option itself shows
  30 only the divisible of 3.
  so ans 30.

• @Abhishek jain
  median is the middle term of numbers in case of odd nos
  & in case of even nos median is (n/2)th term + (n/2 + 1)th term
  & here 2nd term is 5(median)

• (x-10)+5+(x+15)=3x
  x=10
  so total sum =30

• Distnace between House and T junction = 20 x 2 = 40.
  ie., B reached T at 11 am.
  B continued to right after 11 am and travelled upto 2. So distance covered by him = 3 x 40 = 120
  A reached T at 12 noon and travelled upto 2 So distanced travelled by him = 2 x 20 = 40
  So total distance between them = 120 + 40 = 160 km
