Q12.3. If a child receives sweets from Adam, then that child MUST be Lydia.
Q12.4. Johnny reciprocates ONLY with George.
Q12.5. Lydia gives sweets to ALL children.
Answer & Explanation
Q12.1. Yes
Noted that
- Johnny gives sweets to ONLY two children
- All children give sweets toLydia
So one of the two children Johnny gives sweets to has to be Lydia.
Since Johnny and George swap sweets, the two children Johnny gives sweets to are Lydia and George.
Q12.2 No
All we know from the text is that George gives sweets to Johnny and Lydia, but we cannot tell exactly whether he gives sweets to all children. The question is too definite where it could not be concluded with the information we have.
Q12.3 No
Since Lydia receives sweets from ALL children, Adam gives her sweets too. But the question implies that there could be ONLY ONE child who would be receiving sweets from Adam. Hence it is a NO.
Q12.4 No
The other child Johnny gives sweets to, other than George, is Lydia. From the text, we do not know whether Lydia gives sweets to Johnny. Johnny may reciprocate to Lydia and the question is a solid NO.
Q12.5. No
All we know is that Lydia receives sweets from all children. There is no indication she reciprocates.
