The tens digit is y and the units digit is one half of that. What is the value of the number if I reverse its digits ?

The number after reversing the digits is

Step-by-step explanation:

First of all, let us try to learn about representing a 2 digit number.

28 can be written as 20 + 8 OR 2 10 + 8

79 can be written as 70 + 9 OR 7 10 + 9

17 can be written as 10 + 7 OR 1 10 + 7

i.e. if we are given the unit's and ten's digits as U and T, we can write the two digit number as: T 10 + U

Now, it is given that ten's digit is .

Unit's digit is half of that i.e. .

So, the number is

Now, the digits are reversed:

Unit's digit =

Ten's digit =

So, the number after reversing the digits:

The number after reversing the digits is .

two data sets with the same median will not have the same varaibility
