At the beggining of the day some small eggs and some large eggs were on sale at the ratio 3:2. At the end of that day, 260 small eggs and 1/2 of the large eggs were sold. The ratio of the remaining small ones to the remainig large ones became 2:5. How many eggs were there at first?

Answer 1

Beginning eggs:
3/2=L/S or
3S=2L
End eggs:
2/5=(L-1/2L)/(S-260)

Two equations, two unknowns.
