Question

4. Find the least number that should be added to 4000 so that 35 divides the sum exactly.​

Answer 1

Answer:The least number should be added to 40000 so that 55 divides the sum exactly is 40

Solution:

We need to find the least number which should be added to 40000 so that 55 divide the sum exactly

Let’s first divide 40000 by 55  

Hence on dividing we get quotient = 727 and reminder = 15

To get remainder as zero we need to add a number to 15 so that it becomes 55 that is if we add 40 to 15, the number becomes 55 and remainder will be zero.

So 40 must be added to 40000 so that it becomes divisible by 55

We can check by adding 40 to 40000 and the divide it by 55  

= 728, quotient = 78 and remainder = 0

Hence the least number should be added to 40000 so that 55 divides the sum exactly is 40
