Question 5
At New Year, Grandfather, Father and Mother give lucky money to Pi and Ksi. Grandfather gives Pi 100,000 đồng more than Ksi. Father gives Pi 100,000 đồng less than Ksi. Mother gives Pi twice as much as Ksi.
Pi says to his older brother Ksi, “My total lucky money is 100,000 đồng more than yours.” Ksi replies, “If Grandfather had given me as much as Father gave me, I would have received 100,000 đồng more than you.”
Practice completion: the original text has no final question. Using the statements, find (a) Mother’s gift to each child and (b) how much more Father gave Ksi than Grandfather gave Ksi. Explain why the separate gifts from Father and Grandfather cannot be uniquely determined.
