  1. The sum of the digits of two-digit number is 14 and the difference between the two digits number is 2. What is the product of the two digits of the two-digit number ?
    1. 56
    2. 48
    3. 45
    4. None of the above
  1. Correct Option: B

    Let be the ten's digit be x and unit's digit be y.
    So the two digit number = 10x + y ( where x > y )
    According to question
    x + y = 14 ....(i)
    x - y = 2 ....(ii)

    Solving Eqs. (i) and (ii), we get
    x = 8 and y = 6
    ∴ Required product = 8 x 6 = 48
