Question

The following facts are known about an
unknown number X:
1 : The sum of digits of X is 15.
IL : The unit's digit of X is 6.
Then which of the following statement is
certainly true about X?
O X is divisible by 3 but not by 6
O X is divisible by 6 cut not by 9
O X is not divisible by 6 but divisible by 9
O X is divisible by both 6 and 9
11
12
13
C​

Answer 1

Answer:

O X is divisible by 3 but not by 6

Step-by-step explanation:

Test of divisibility:

If the sum of digits in a number is 3 or

multiples of 3 then that number is divisible

by 3 and vice versa

Answer 2

Answer:

option 2: X is divisible by 6 but not by 9

Let a be the ten's digit and b be the unit's digit

A.T.Q:

a+b=15

a+6=15

a=9

the number X = 10(a)+b=96

X = 96

96 is divisible by 6 but not by 9

hence, X is divisible by 6 but not by 9 - option 2
