When a pupil makes one of these on Revision Workshop, the marking engine names the mistake and explains it, instead of just marking the answer wrong.

Gave total amount transferred not split
Correctly found the total amount Amir gave away (£60) but did not split this between what went to Beth and what went to Carla specifically.
Confused recipients of transfer
Correctly found the two transferred amounts but assigned the amount that actually went to Beth (£20) to Carla instead.
Makes jess pay full cost not the remainder
Gave Carly's FINAL amount (£12, from $7+5$ ) as the answer, instead of working out what Amy must have started with so that giving away £7 still leaves her with that same final amount.
