4.28 and -3.28 are two numbers on a real number line.If 1 is added to both the numbers,then which of the following is true?
a, distance between the two new number is 2 units MORE than the distance between 4.28 and -3.28
b, distance between the two new number is 2 units LESS than the distance between 4.28 and -3.28
c, distance between the two new number is 2 units EQUAL than the distance between 4.28 and -3.28
d, NONE

• since 1 is added to both the numbers
  then from negative side it will decrease by 1 unit
  and from positive side it will increase by 1 unit
  
  so the distance remains same
  
  so option c is correct

• let us try to understand with line
  -------|---------------|----------------------|------------
  -3.28 0 4.28
  
  if add 1 to both number
  -------------|-----------|---------------------------------|--------
  -2.28 0 5.28
  
  4.28-(-3.28)=7.56
  by adding 1 to both number
  4.28+1=5.28
  -3.28+1=-2.28
  5.28-(-2.28)=7.56

• Option "C"

• Option:- C
• 9 years agoHelpfull: Yes(3) No(2)
• ans. C
  distance between 4.28 and -3.28 is 7.56
  distance between 4.28+1 and -3.28+1 is 7.56
  both are equal.

• option a; distance btw two new numbers is 3
  distance btw two old numbers is 1
  hence new number distance is 2 units more

• option a
  
• 9 years agoHelpfull: Yes(1) No(9)
• NONE.D option
• 9 years agoHelpfull: Yes(1) No(7)
• distance between old point is=1
  distance(after adding one to both points) between new points is=3
  so OPTION A.only true
  i.e.distance between new point is 2 unit more than old.

• Option d
  
  
  
  
  
• 9 years agoHelpfull: Yes(0) No(3)
• Ans)c ,because we are adding +1to both 4.28 and -3.28 so distance is equal between 5.28 to -2.28 and 4.28 to -3.28.
• 8 years agoHelpfull: Yes(0) No(0)
• D, None. Because both the numbers are incremented by 1, so the difference has to be equal
• 5 years agoHelpfull: Yes(0) No(0)
• c
  4.28-(-3.28)=7.28
  4.28+1=5.28
  -3.28+1=-2.28
  5.28-(-2.28)=7.28
