We are given several relationships between the amounts earned by the individuals:
- Jerome got less money than Tommy, which means Tommy earned more than Jerome.
- Jerome and Tommy together got the same amount as Albert and David taken together, meaning their earnings were balanced in this way.
- Albert and Tommy together got less than David and Jerome taken together, meaning David and Jerome's earnings were greater.
By comparing these relationships, we can infer:
- Since Jerome earned less than Tommy, it suggests that Tommy may have plucked more mangoes and earned more.
- Albert and Tommy earned less than David and Jerome combined, which places David as a higher earner compared to Albert and Tommy.
- Given the relationships, Albert earned the most pocket money and Tommy plucked the least number of mangoes. Thus, the correct answer is (D).
