Question

What is the number of integers from 1 to 1000, inclusive that are not divisible by 11 or by 35?

Answer 1

✨ HEY MATE ✨

➡️Here is a way to find out :-


Calculate the no. of terms from 1 to 1000 (inclusive) that are divisible by 11 or 35 or both.

1.) Total no. of terms divisible by 11 are 90. We can calculate this by finding the first and last terms, which are 11 & 990 respectively. Then we will find the total no. of terms by using equation 

Last Term = a + (n-1)d where a=11, d=11, Last Term=990. 

So, n=90.
