Kate is 5 years older than Lenny. Lenny is 2 years younger than Maria. Maria is twice as old as Norman. If Norman is 10 years old, how old is katie?

K = Kates age

L = Lannys age

M = Marias age

N = Normans age

K = L + 5

L = M - 2

M = 2 N

N = 10

M = 2 N

M = 2 * 10 = 20

L = M - 2 = 20 - 2 = 18

K = L + 5 = 18 + 5 = 23

To find Kate's age, we need to follow the given information step-by-step:

1. We know that Norman is 10 years old.
2. Maria is twice as old as Norman, so she is 10 * 2 = 20 years old.
3. Lenny is 2 years younger than Maria, so Lenny is 20 - 2 = 18 years old.
4. Kate is 5 years older than Lenny, so Kate is 18 + 5 = 23 years old.

Therefore, Kate is 23 years old.

To find Kate's age, we can follow these steps:

1. We are given that Norman is 10 years old, so we'll note this information.
Norman = 10 years old

2. We are also given that Maria is twice as old as Norman, so we'll calculate Maria's age.
Maria = 2 * Norman
Maria = 2 * 10
Maria = 20 years old

3. It is mentioned that Lenny is 2 years younger than Maria. So, we'll calculate Lenny's age.
Lenny = Maria - 2
Lenny = 20 - 2
Lenny = 18 years old

4. Kate is 5 years older than Lenny. Thus, we'll calculate Kate's age.
Kate = Lenny + 5
Kate = 18 + 5
Kate = 23 years old

Therefore, Kate is 23 years old.
