Word Problem

Debra and Giselle have some playing cards. After Giselle gives 21 playing cards to Debra, Debra has 40 more playing cards than Giselle.
a) Who had more playing cards at first?
b) How many more?

Please kindly help.
Thanks.

If Debra had 40 more playing cards than Giselle after Giselle gives Debra 21 cards, then
Debra would have had more playing cards at first.  19 more cards.
