Answer 2

Answer:

Step-by-step explanation:

numbers after 100 which is  divisible by 7 is 105 and biggest three digit number divisible by 7 is

1000÷7 has 6 as reminder

∴ 1000–6=994

994=7*142

105=7*15

Therefore between 100 and 1000 there will be

142–15=127 numbers divisible by 7 and considering 105 there are 128 such numbers.  

so,

There are total 889 numbers between 100 and 1000 out of which 128 numbers are divisible by 7

∴ Remaining numbers i.e. 899 - 128 = 771 are not divisible by 7.
