The first equation shows:
+ + = 30Since the three puppies are identical:
30 ÷ 3 = 10
So:
= 10
Step 2: Find the value of the pineapple
The second equation is:
+ 
+ = 20Substitute the puppy’s value:
10 + + = 20Subtract 10 from both sides:
+ = 10Divide by 2:
= 5
Step 3: Verify with the third equation
The third equation says:
− = 5Using the values we found:
5 − 10 = -5This does not equal 5.
That means the third equation is incorrect and is intentionally included to mislead the solver. The values established by the first two equations are mathematically consistent, while the third one contradicts them.
Step 4: Solve the final expression
The last line is:
+ × Using:
- = 10
- = 5
Remember that multiplication comes before addition.
First calculate:
5 × 10 = 50Then add the puppy:
10 + 50 = 60
Final Answer
60
Note: The third equation is inconsistent with the first two. If the puzzle intended all equations to be valid, it contains an error. Based on the first two equations and standard mathematical rules, the correct final answer is 60.
