Who is taller, Sam or Kate?
By how much?
What is the height of the stool?
Age 11 to 13
These calculations are in code.
Each of the letters A to F stands for a different digit.
A+A=B CxC=BD C+C=DB AxC=EF What is the code answer to these?
a. AA+CC c. ABVE b. AAxC d. BB-EC
Taller and taller Sam is 10cm taller than Kate.
The height of the stool is 45cm.
A = 4. B = 8, C = 9, D = 1, E = 3, F = 6.
If C + C = DB, then D = 1.
If C x C = BD and D=1, then C=9 and B = 8.
If A + A = B, then A = 4.
If A x C = EF, then E = 3 and F = 6.
a. AA+ CC is DAE.
b. AA x C is ECF.
c. AB .-.J E is DF.
d. BB - EC = AC
