Five girls live in the same apartment building. To determine the age of each girl, write each clue as an equation or an equality.
:
1. All five girls are older than 10 but younger than 20.
All girls >10, <20
:
2. Karen is older than Angela but younger than Janet.
K > A; K < J
and therefore
J > 14
:
3. Janet's age is halfway between Tamara's age and Angela's age.
J =
Since J > 14, & J > K & A < K, & J's age is odd,
it has to half-way between 12 and 18
J = 15 yrs
:
4. the ages of all the girls except Janet are even numbers.
Ages. 12, 14, 16, 18 except J
:
5. Susan is neither the oldest nor the youngest.
S = 14 or 16
:
6. Karen is as much older than Angela as Tamara is older than Susan.
K - A = T - S
From this we know T = 18, S = 16
:
7. No two girls are the same age.
:
The following seems to fit all the clues
A = 12
K = 14
J = 15
S = 16
T = 18
