Answer 1

Answer:

One Hundred and Eleven 111

Answer 2

Answer:

111

Step-by-step explanation:

To find the 9 multiples between 1 to 1000

we have to form a A.P. series with d=9

9,18,27,36,…….,999

We have to find the value of n=number of numbers in the series.

Tn=a+(n-1)d

Here a=9,d=9

999=9+(n-1)9

==>(n-1)9=990

==>n-1=110

Therefore There are 111 multiples of 9 in between 1 to 1000.
