Mrs Tan put some popsicles into her cooler box for a party. Damien took \( {1 \over 5}\) of
them but returned 5 popsicles into the color. Alice then took \({2 \over 3}\) of the
remaining popsicles and an additional 3 from the color. Ben then took \( {1 \over 4}\) of
the remaining popsicles. There were 21 popsicles left in the cooler in the end.
How many popsicles did Mrs Tan put into the cooler box at first?
+36916 x = origianl amount
x - 1/5x + 5 after d = 4/5 x + 5 remaining
(4/5x+5) - (2/3 ( 4/5 x + 5) +3 ) = 4/15 x - 4/3 remaining after A
then Ben takes 1/4 leaving 3/4 3/4 (4/15 x - 4/3) = 21
x = originally 110
