For a two digit number, the single digit number is 3 larger than the ten digit number. The product between the original number and the number obtained after the transposition of the single digit number and the ten digit number is 574, and the two digit number can be obtained
Let the two digits be 10A + B,
a+3=b
(a+10b)(10a+b)=574
Substituting (11a + 30) (11a + 3) = 574
A = 1, so B = 4 is 14
