  • Let's solve this problem without using any mathematical formula of Arithmetic Progression. This gives us the speedy answer which is so required in the competitive exams where there is a constraint of time.
    The greatest three digit number is 999.
    And 999/19 = 52.57.
    This implies upto 999, a total of 52 numbers are completely divisible.
    Subtracting from this, number of two- digit numbers also divisible by 19 taken into account in the previous calculation, i.e 19,38,57,76, and 95, we get :
    52-5 = 47 
    Thus there are 47 such 3 digit numbers in all.
