उत्तर :
व्याख्या :
Let the 5 digit number be represented by abcde. Then the 6 digit number, 1abcde x 3 = abcde1 (another 6 digit number) Now let Y = abcde Then (100000 + Y) x 3 = (Y x 10) + 1 300000 + 3Y = 10Y + 1 7Y = 299999 Y = 299999 ÷ 7 = 42857

प्र: Which number multiplied by itself will give the output as 12345678987654321 ? 1945 0

उत्तर :
