Question

if 21y5is a multiple of 9,y is a digit, what is the value of y

Answer 1

Hi there !!
Here's your answer


Given that ,
21y5 is a multiple of 9 where y is a digit

We know,
for a number to be divisible by 9 , the sum of digits should be a multiple of 9

So,
2 + 1 + y + 5 = multiple of 9

8 + y = 9

y = 9 - 8 = 1

y = 1

Thus,
the value of y is 1
