Jim had 4/5 as many stamps as Kenny. After Jim bought another 52 stamps and Kenny gave away 78 stamps to his brother, Kenny had 1/3 as many stamps as Jim. How many stamps did both of them have altogether at first?

Answer 1

J = 4/5 K
J+ 52 = 3 (K-78)
4 K/5 = 3 K -234 -52
4 K = 5 (3 K - 286) = 15 K - 1430
11 K = 1430
K = 130
J = 4/5 * 130 = 104
add them 234
