Initially family earned 100\$ and Lee earned \$60

After 20% jump Lee earned 72

So % of lees = 72/112 (since family sal still is 40 \$ whereas leesa is 72)

A

my approach is solving by equations rather than putting values for such problems-

let Lee's income in may = L
Family income = X+ L where x is the other members' income.
in may L = 0.6(X + L) ===> X = 2L/3
in june Lee's income = 1.2L
In june family's income = X + 1.2L
ratio of Lee's income to the family's income in june = 1.2L/(X+1.2L) = 9/14
