A four digit number is such that the product of all of its digits is 126. The sum of all the digits is equal to the 2 digit number formed by using thousands digit and tens digit (Thousand digit in tens place & ten digit in units place) which in turn is equal to 19. Then difference of units and thousand place of the number is, given that this difference is positive.

• the number is 1792.
  Let the number be represented as 1000x+100y+10z+t
  acc to ques,
  xyzt=126
  x + y + z + t = 10x + z = 19
  so, number in thousands and tens place are 1 and 9 respectively.
  the remaining factor is 14 which is 7*2
  So the number is 1792.
