Question

What shall be the value of x+y for the number 21x93y587 divisible by 9​

Answer 1

Answer:

x + y should be 10 or 1

Step-by-step explanation:

Given that the digits given above have a sum of 35 so adding 10 to it would make it 45 which is perfectly divisible by 9 or you can change the digits by making it 0+1 which gives 1 as answer and the number would be 36 which is also perfectly divisible by 9

A number is divisible by 9, if the sum is a multiple of 9 or if the sum of its digits is divisible by 9.
