    the sum of their ages be after one year?

    After a year, both of them will be 1 year older. Thus the sum of their ages must be 2 years
    more. That is 12 years.
    Problem 2:
    A dragon has three heads. Every time a hero cuts off one head, tree new heads emerge.
    The hero cuts one head off, and then cuts off one more head. How many heads does the

    two letters of the word KANGAROO such that the first letter is a consonant and the second
    letter is a vowel. How many different baby names can be composed?

    Solution:
    The first letter must be either K,N,G,R. The next letter must either be A or O. Thus there are
    4×2=8 ways to name a baby Kangaroo.

    Problem 4:
    Laura, Iggy, Val and Kate want to be in one photo together. Kate and Laura are best friends
    and they want to stand next to each other. Iggy wants to stand next to Laura because he

    Solution:
    Let Laura = L, Iggy=I, Val=V, Kate =K

    Given the conditions above, the possible arrangements are ILKV, VILK, VKLI and
    KLIV. 4 possible arrangements.
    Problem 5:
    Sophie draws butterflies: a blue one, then a green, then a red, then a black, then a yellow, a
    blue, a green, a red, a black, and so on. What color is the 17 butterfly?
    th

    Solution:
    Observe that there is a pattern in Blue,green,red,black,yellow. The color of Butterflies
    repeats every 5 draws. Following the pattern. 17=5×3+2. Thus the color must be the same
    as the second draw. The answer is Green.
    Problem 6:
    Tomas found an old book in the attic. When he opened it, there was page 24 on the left
    side, and page 55 in the right. How many sheets of paper are missing between these two
    pages?

    Solution:
    Every page has two page numbers. Front and back. The missing pages are 54-25+1=30.
    We need to divide that by 2 to get the number of pages. Hence the answer is 15 pages.
    Problem 7:
    Problem 7:

    Lea owns 1 white, 2 black and 3 brown pigs. If all of these pigs could talk, how many of

    Problem 8:
    What is the tens digit of the largest four-digit even number which uses each of the digits
    5,7,8, and 9 exactly once?

    Solution:
    Before we can answer the question we need to know first the largest 4-digit even number
    that can be formed using the given digits. Since there is only 1 even digit 8. The one’s digit
    must be 8. To maximize the number, the first digit must be 9,followed by 7 and 5. Thus the
    largest number here is 9758. 5 is the ten’s digit.
