What is the sum of integers from 1 to 100 which are divisible by 3 or 5?
The sum of the integers from 1 to 100 which are divisible by 3 and 5, is (1) 2317 (2) 2632 (3) 315 (4) 2489. Solution: LCM of 3 and 5 is 15. Hence option (3) is the answer.
How many numbers from 1 to 100 are there each of which is not divisible by 4 but also has 4 as a digit?
7 such
Detailed Solution Therefore, the required numbers are 4, 24, 40, 44, 48, 64, 84. Clearly, there are 7 such numbers. Hence, there are 7 numbers from 1 to 100 each of which is not only exactly divisible by 4 but also has 4 as a digit.
What is the sum of the integers from 1 to 100 that are divisible by 2 or 5?
3050
Hence, we have obtained the sum of integers from 1 to 100 which are divisible by 2 or 5 as 3050. Therefore, the correct answer to the question is option (b) 3050.
How many numbers between 1 and 100 are not divisible by 2 or 3 or 7 or 5?
We know that there are 25 prime numbers between 1 and 100. Since 2, 3, 5 and 7 are prime numbers, total prime numbers, which are not divisible by 2, 3, 5 and 7, are (25 – 4) 21.
How many numbers between 1 and 100 are divisible by both 3 and 2?
So, the number of numbers between 1 and 100 which are divisible by both 2 and 3 is (33+49-16) or 66. Therefore, the required number is (98-66) or 32.
How many numbers between 1 and 100 are divisible by both 3 and 4?
Originally Answered: How many numbers from 1 to 100 (inclusive) are divisible by both 3 and 4? Find how many numbers between 1 and 100 that are exactly divisible by 12 (3*4 = 12). The numbers are: 12, 24, 36, 48, 60, 72, 84 and 96.
How many integers are there in between 1 and 100 which is not only exactly divisible by 8 but also has 8 as a digit?
∴ The required numbers are 4, 24, 40, 44, 48, 64, 84.
How many integers are there in between 1 and 100 which have 8 as digit but not exactly divisible by 8?
