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
Read Solution (Total 14)
-
- 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 - 10 years agoHelpfull: Yes(16) No(0)
- 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 - 10 years agoHelpfull: Yes(9) No(1)
- none.option d

- Option "C"
- 10 years agoHelpfull: Yes(4) No(0)
- Option:- C
- 10 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. - 9 years agoHelpfull: Yes(3) No(0)
- option a; distance btw two new numbers is 3
distance btw two old numbers is 1
hence new number distance is 2 units more - 8 years agoHelpfull: Yes(2) No(2)
- option a
- 10 years agoHelpfull: Yes(1) No(9)
- NONE.D option
- 10 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. - 9 years agoHelpfull: Yes(1) No(2)
- Option d
- 10 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.
- 9 years agoHelpfull: Yes(0) No(0)
- D, None. Because both the numbers are incremented by 1, so the difference has to be equal
- 6 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 - 4 years agoHelpfull: Yes(0) No(0)
