Imagine linking four numbers on this grid. The
links can go up or down or sideways, but not
diagonally. What is the greatest total you can
make? What is the smallest total you can
make?

Fraction fun !
A fraction has the denominator
greater than its numerator by 6. But if
you add 8 to the denominator, the
value of the fraction would then
become 1/3.
Can you find this fraction?

Missing signs
(37 ------ 21) ------ 223 = 1000
(756 ------ 18) ------ 29 = 1218
27 ------ (36 ------ 18) = 675
31 ------ (87 ------ 19)= 2108
Each box represents a
missing sign ( +, -, x, or ÷)

Missing signs
(37 -- x -- 21) -- + -- 223 = 1000
(756 -- ÷-- 18) – x -- 29 = 1218
27 -- + -- (36 – x -- 18) = 675
31 -- x -- (87 -- _ -- 19)= 2108
Each box represents a
missing sign ( +, -, x, or ÷)

Logic “Aha”!
6 Questions
Each Q = 2.5 minutes
Total time = 15 minutes

Colors and names
There are 3 gentlemen in a meeting: Mr.
Yellow, Mr. Green and Mr. Brown. They are

Alphabet soup
Alphabets A through R are printed above the box,
in the box, and beneath the box.
Can you continue on for S to Z and
place them correctly according to the scheme ?
Above the box, the alphabets have only lines.
In the box, they have lines and curves.
Below the box, they have only curves.

Secret Code
Each letter stands for one of these digits –
1,3,4,6,8,9
A + A = B A x A= DF
C + C = DB C x C= BD
A + C = DE A x C= EF
Work out the following:
E + F F + B
E x F F x B

Secret Code
A cannot be 1 as there is no 2.
A cannot be 3 because A x A is a 2-
digit number
A has to 4; B = 8
DF = 16; D = 1; F = 6
C + C = 18; C x C = BD = 81; C = 9
DE = 13; E = 3

Alphabet magic square
Place the alphabets A to I
the 3 x 3 box. E is to the right of C.
A is to the right of G which is above B,
which is to the left of F. I is above D
which is to the left of G.
