1.	If 231325x is divisible by 9, then find the least value of x.
Answer» $<klux>GIVEN</klux> \: <klux>NUMBER</klux> \: 231325\pink {x}$ $\underline { \blue { Divisibility \: rule \:of \:9 :}}$ *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., $\red { Least \: value \: \pink {x} } \green { = 2 }$ •••♪
