Answer 2

Number are not divisible by 5 =200

Given:

Whole numbers between 1 and 250.

To find:

How many are not divisible by 5.

Formula used:

$n^{th}$ term in arithmetic progression = A+ (n-1)d

      Where    A = First term

                    n = no. of terms

                    d = common difference

Explanation:

Let the whole number between 1 and 250 which is divisible by 5 is "x"

Then number between 1 and 250 which is not divisible by 5 is "250-x"

Divisible by 5 is

5,10,15,20,25.............250 This is arithmetic progression.

                    A = First term = 5                    

                    d = common difference =10-5 =5

                    $n^{th}$ term = 250

$n^{th}$ term = A+ (n-1)d

     250  = 5 + (n-1)5

   250-5 = 5n-5

   245 +5 = 5n

        250 =5n

          n= $\frac{250}{5}$ = 50

So  whole number between 1 and 250 which is divisible by 5 is "50"

whole number between 1 and 250 which is not divisible by 5 = 250-50

                                                                                                      =200

Number are not divisible by 5 =200
