WebMay 11, 2024 · Naive Approach: The simple approach is to iterate through all the numbers in the given range [L, R], and for every number, check if it is divisible by any of the array elements. If it is not divisible by any of the array elements, increment the count. After checking for all the numbers, print the count. Time Complexity: O((R – L + 1)*N) Auxiliary … WebQues: Identify the number that is divisible by 3. Choices: A. 225 B. 125 C. 205 D. 148 Correct Answer: A. Solution: Step 1: If the number has digits whose sum is divisible by 3, then it is divisible by 3. [Divisibility rule] Step 2: 2 + 2 + 5 = 9 [Add the digits in the number 225.] Step 3: 9 is divisible by 3. So, 225 is divisible by 3. WebThe following steps are used to check the divisibility test of 7: Step 1: Identify the ones place digit of the number and multiply it by 2. Step 2: Find the difference between the number obtained in step 1 and the rest of the number. Step 3: If the difference is divisible by 7, then the number is divisible by 7. bohemia school
