Question

What should be the highest value that must be assigned to # so that the number 10114#5 is exactly divisible by 7?

Answer 1

To know the highest value that must be assigned to #, we need to take digits from 9 to 0 and further check the divisibility by 7.

First, take 9 in the place of #, thus the number becomes 1011495.

But this number is not divisible by 7.

Similarly, check for 8,7,6,5.

Thus, you will get 6 as the highest value assigned to #.

Answer 2

Answer:

Step-by-step explanation: divisibility rule for 7 is double the last digit and subtract from the remaining digits
