Re: Another tricky question
1. Maria has 19 cars, if Maria and Nadim have 35 in total, then Nadim has 35-19=16
2. add all the numbers up for the total
3. If nadim has 16 and Gordon+Nadim have 29 in total, then Gordon must have 29-16= 13
hope this is right, cant see why not though, someone else wanna check the logic please

Maria and Nadim = 35
If Maria has 19 Nadim must have 16
If Nadim has 16, Gordon must have 13
N 16
M 19
G 13
Total = 48 not 43

Re: Another tricky question
indeed, add up the individual numbers up, you cant answer 2 without answering 1 & 3 first..seems a strange order

Re: Another tricky question
You can answer question 2 by adding Maria's 19 onto Nadim and Gordon's 29
