    [SIZE=+1]Kris found a treasure box. To open the box, she had to put four numbers in their correct order, using the following clues:[/SIZE]


    *The first and second numbers are prime.
    *The third number is a multiple of the second number.
    *The second number is even.
    *The third number is more than nine and less than twenty.
    *The first number is less than ten.
    *The fourth number is the least common multiple of the first two numbers.
    *The fourth number is the largest of all four numbers.
    *The first number is more than three times the second number.
    *The third number is one more than the sum of the first two numbers.



    [SIZE=+1]She opened the box and found a treasure equal to 1000 times the sum of the four numbers. How much was the treasure worth? [/SIZE]

    මෙම අකුරු 0-9 දක්වා එක් සංඛ්‍යාවක් පමණක් නිරූපණය කරයි නම් A,B,C,D,E වල අගයන් සොයන්න.

    Because there is no carry for A x 4, we know A = 2, 1, or 0. Now,A=0 implies E= 1, 2, or 3 (due to carry from B x 4).
    But, A=0 implies E=5 since E x 4 ending in 0. Thus, A must be 1 or 2.
    But, A must be even by E x 4, which implies A=2 and E is either 3 or 8.
    But E=3 cannot work with A x 4 where A=2. Thus, E=8.


    We note that there is no carry from B x 4, which implies B = 0 or 1.

    But, B must equal 1 as (D x 4) + 3-carry is odd...which implies D = 7.
    Finally, a carry of 3 is necessary to make D=7 for B x 4, which implies C=9
