 Hello and welcome to the session. In this session we discussed the following question which says find the largest four digit number divisible by 24. Let's see its solution now. We have to find the largest four digit number which is exactly divisible by 24. For this, first let's see which is the largest four digit number. This is equal to 9999. So first of all we will divide the largest four digit number which is 9999 by 24. Now 24, 4 times is 96. We subtract 96 from 99. We get 3. We take this 9 down. Now 24, 1 times is 24. We subtract these two numbers. We get 15. We take this 9 down. So we have 159 and 24, 6 times is 144. We subtract these two. We get the remainder as 15. So when we divide the largest four digit number by 24 we get the remainder as 15. Now we subtract 15 from the largest four digit number that is 9999 and we get 9984. And this number, 9984 is divisible by 24. As we say the largest four digit number divisible by 24 is 9984. So this is our final answer. This completes this session. Hope you have understood the solution of this question.
