Marlon had 42 lollipops in the beginning. On his way home, he saw Emily and gave her 2/3 of his lollipops. Then, Marlon kept 4 lollipops and gave the rest to Lou. How many lollipops did Lou receive?
Marlon gave Emily 42 x 2/3 = <<42*2/3=28>>28 lollipops.
So, he only had 42 - 28 = <<42-28=14>>14 lollipops left.
After keeping 4, Marlon gave 14 - 4 = <<14-4=10>>10 lollipops to Lou.
