Question

Jess and George each have some money. If Jess spends $3, the ratio of the amount of money Jess has to the amount that George has will become 2 : 5. If George spent $3, the ratio of the amount of money Jess has to the amount that George has will become 8 : 13. How much money does George have at first?

Answer 1

so, what have they told you?
(j-3)/g = 2/5
j/(g-3) = 8/13
now solve for g.
