From1thru9,the sum is45,10 thru19,the sum is55,20 thru29is65,and30thru39is75.Thus the sum of the digits is45+55+65+75+4+5+6+7+8=240+30=270,and thus N is divisible by9. Now.refer to the above solution N=4(mod5)andN=0(mod9)From this information,we can conclude this i...
Thus the sum of the digits is 45+55+65+75+30=270, so the number is divisible by 9. We notice that the number ends in " 4 ", which is 9 more than a multiple of 5 . Thus if we subtracted 9 from our number it would be divisible by 5 , and 5⋅9=45.结果...
