Question

8. If three digit number 24x is divisible by 9, the value of x is:

a) 1

b) 2

c) 3

d) 4​

Answer 1

Answer:

The answer is c)3

Step-by-step explanation:

Since 24x is divisible by 9, sum of its digits, i.e., 2 + 4 + x should be divisible by 9, i.e., 6 + x should be divisible by 9. This is possible when 6 + x = 9 or 18, .... But, since x is a digit, therefore, 6 + x = 9, i.e., x = 3.

Answer 2

Answer:

3

Step-by-step explanation:

for the number to be divisible by 9

it should be a multiple of three and the digiya of the number should add up to a multiple of 9

here 243 ...2+4+3 =9 ..where 9 is a multiple of 9
