(2) 1 (3) 2 (4) 3
(1) 4​

Answer 1

Answer:

1

Step-by-step explanation:

10*4

1+0+*+4= 14

14 is close 15 which is a multiple of 3

So, 1+0+*+4 is therefore solved and the number is

$number \: = \: 1$

Answer 2

Answer

option (2) 1 or option (1) 4

Step-by-step explanation:

For a number to be divisible by 3, summation of all the digits of the number should be a multiple of 3.

For eg: 273 is divisible by 3, because 2+7+3 = 12 is a multiple of 3.

In the similar manner for 10*4 to be divisible by 3 , 1+0+*+4 should be a multiple of 3 hence 5+* should be a multiple of 3. So the answer should be 1 because 5+1= 6 is multiple of 3. Also 4 can be an answer too as 5+4= 9 is also a multiple of 3. Hence the number would be either 1014 or 1044
