Susy had 2/3 as much money as Mary at first. After receiving 1/2 of Mary's money, Susy had $210. How much money did Susy have at first

Answer 1

Let us assume that Mary had $x to start with. Hence Susy had $(2/3)x

1/2 of Mary's money = $x/2

Now Susy has (2/3)x+x/2=7x/6

$210=7x/6

Therefore, x=(210*6)/7=$180

Therefore, to start over with, Susy had $2x/3 = $120
