Q) How many cars does Nadim own?
Q) How many cars do the 3 children have in total?
Q) How many cars does Gordon own?

Answers 16,43 and 13.

Many thanks.

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

Nadim + Gordon = 29
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

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

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