Leila invited some friends on her birthday. Her mother placed some puris on a table to be served. If Leila places 4 puris in each plate, 1 plate would be left empty. But, if she places 3 puris in each plate, 1 puri would be left. Find the number of plates and puris on the table. Please don’t spam.
Answer:
Let the total number of puris be x, and the plates be y.
From the first given, if she places 4 puris in each plate, one plate would be missing. If we put these words into an equation:
(1)
From the second given, if she places 3 puris in each plate, 1 puri will be given. If we put these words into an equation:
(2)
From equations (1) and (2):
.
Therefore, the number of plates is 5.
Now solve for x:
Therefore, the number of puris is 16.
