Office - In front of visawa garden gate no.2, Muni Education, Industrial Area, Nanded Detailed Solutions -- There are some flowering trees in a garden. Each tree bears many flowers with the same number printed on it. Three children took a basket each to pick flowers. Each basket has one of the numbers, 3, 4 or 9 on it. Each child picks those flowers which have numbers divisible by the number on his or her basket. He/She takes only 1 flower from each tree. Can you tell which numbers the flowers in each basket will have ? Divisibility rule of 3: A number is divisible by 3 if the sum of its digits is divisible by 3. Flowers in basket number 3: 72, 90, 108, 111, 123, 249, 336, 369, 432, 435, 450, 666, 960, 999 Divisibility rule of 4: A number is divisible by 4 if the number formed by the last two digits is divisible by 4. Flowers in basket number 4: 72, 108, 220, 336, 356, 432, 960 Divisibility rule of 9: A number is divisible by 9 if the sum of its digits is divisible by 9. Flowers in basket number 9: 72, 90, 108, 369, 432, 450, 666, 999 Divisibility Rule of 1 Every number is divisible by 1. Divisibility rule for 1 doesn’t have any condition. Any number divided by 1 will give the number itself, irrespective of how large the number is. For example, 3 is divisible by 1 and 3000 is also divisible by 1 completely. Divisibility Rule of 2 If a number is even or a number whose last digit is an even number i.e. 2,4,6,8 including 0, it is always completely divisible by 2. Example: 508 is an even number and is divisible by 2 but 509 is not an even number, hence it is not divisible by 2. Procedure to check whether 508 is divisible by 2 or not is as follows: Consider the number 508 Just take the last digit 8 and divide it by 2 If the last digit 8 is divisible by 2 then the number 508 is also divisible by 2. Divisibility Rules for 3 Divisibility rule for 3 states that a number is completely divisible by 3 if the sum of its digits is divisible by 3. Consider a number, 308. To check whether 308 is divisible by 3 or not, take sum of the digits (i.e. 3+0+8= 11). Now check whether the sum is divisible by 3 or not. If the sum is a multiple of 3, then the original number is also divisible by 3. Here, since 11 is not divisible by 3, 308 is also not divisible by 3. Similarly, 516 is divisible by 3 completely as the sum of its digits i.e. 5+1+6=12, is a multiple of 3. Divisibility Rule of 4 If the last two digits of a number are divisible by 4, then that number is a multiple of 4 and is divisible by 4 completely. Example: Take the number 2308. Consider the last two digits i.e. 08. As 08 is divisible by 4, the original number 2308 is also divisible by 4. Divisibility Rule of 5 Numbers, which last with digits, 0 or 5 are always divisible by 5. Example: 10, 10000, 10000005, 595, 396524850, etc. Divisibility Rule of 6 Numbers which are divisible by both 2 and 3 are divisible by 6. That is, if the last digit of the given number is even and the sum of its digits is a multiple of 3, then the given number is also a multiple of 6. Example: 630, the number is divisible by 2 as the last digit is 0. The sum of digits is 6+3+0 = 9, which is also divisible by 3. Hence, 630 is divisible by 6. Divisibility Rule of 8 If the last three digits of a number are divisible by 8, then the number is completely divisible by 8. Example: Take number 24344. Consider the last two digits i.e. 344. As 344 is divisible by 8, the original number 24344 is also divisible by 8. Divisibility Rule of 9 The rule for divisibility by 9 is similar to divisibility rule for 3. That is, if the sum of digits of the number is divisible by 9, then the number itself is divisible by 9. Example: Consider 78532, as the sum of its digits (7+8+5+3+2) is 25, which is not divisible by 9, hence 78532 is not divisible by 9. Divisibility Rule of 10 Divisibility rule for 10 states that any number whose last digit is 0, is divisible by 10. Example: 10, 20, 30, 1000, 5000, 60000, etc.
