Re: This year Henry will save a certain amount of his income [#permalink]
Income = Save + Spend
Let save be X
Let spend be Y

Income = X + Y
we want x*(1+r) = 1/2Y
-> Y = 2*x(1+r)
-> Income = x + 2*x(1+r)
-> Income = x + 2x + 2xr
-> Income = x (1+ 2 + 2r)
-> Income = x(3 + 2r)
-> x(amount saved) is 1/(3+2r) of in come
