Question

If 231325x is divisible by 9, then find the least value of x.​

Answer 1

$Given \: number \: 231325\pink {x}$

$\underline { \blue { Divisibility \: rule \:of \:9 :}}$

The given number is divisible by 9, only if the sum of the digits is multiple of 9 .

$Here , Sum \:of \:the \:digits \: of \:231325\pink {x} \\= 2+3+1+3+2+5+\pink {x} \\= 16 + x$

$Now, 16 + \pink {x} = 18 \\(Least \:multiple \:of \:9 )$

$\implies \pink {x}= 18 - 16$

$\implies \pink {x} = 2$

Therefore.,

$\red { Least \: value \: \pink {x} } \green { = 2 }$

Answer 2

Step-by-step explanation:

This is ur answer

thanks for question

according to divisibility rule of 9 we will do sum of digits:

2+3+1+3+2+5+x

= 16+x

Now, the least multiple of 9 is 18 bcoz it is greater than 18. whereas if we take 9 multiple then it would not be able to Subtract and answer will come in negative.

so, 16+x= 18

x= 18-16

x= 2

thanks

least value of x is 2
