3. Jo’s age plus Mo’s age is 27. Jo’s age plus Flo’s age is 38. Mo’s age plus Flo’s age is 33. How old is FLO?
- 11
- 16
- 22
- 9
- 5
The correct answer and explanation is:
The correct answer is 16.
Explanation:
We are given the following equations based on the problem:
- J+M=27J + M = 27 (Jo’s age + Mo’s age)
- J+F=38J + F = 38 (Jo’s age + Flo’s age)
- M+F=33M + F = 33 (Mo’s age + Flo’s age)
We need to determine Flo’s age (FF).
Step 1: Solve for Jo’s Age
We can add equations (1) and (2): (J+M)+(J+F)=27+38(J + M) + (J + F) = 27 + 38 2J+M+F=652J + M + F = 65
Using equation (3), substitute M+F=33M + F = 33: 2J+33=652J + 33 = 65 2J=322J = 32 J=16J = 16
Step 2: Solve for Mo’s Age
From equation (1): 16+M=2716 + M = 27 M=11M = 11
Step 3: Solve for Flo’s Age
Using equation (3): 11+F=3311 + F = 33 F=16F = 16
Thus, Flo’s age is 16 years.
Verification:
To confirm, we check if our values satisfy all given conditions:
- J+M=16+11=27J + M = 16 + 11 = 27 ✅
- J+F=16+16=38J + F = 16 + 16 = 38 ✅
- M+F=11+16=33M + F = 11 + 16 = 33 ✅
All equations hold true, so the answer is correct.
Final Answer:
Flo is 16 years old.
