I like to give things real values to help visualize it.

So say their family made $100 in May, So Mrs. Lee made $60 of that and everyone else made $40.

If she made 20% more in June, she made $60 x 1.2 = 72$

So 72 + 40 = 112

72/112 = .643 or 64%

Sorry....a correction to the earlier post

i assumed that families income is constant
but its stated that rest of families income is constant

so it will be .72x/1.12x*100 ~64%
