If Mrs Brown gets her class of 21 children to stand in a circle followed by choosing the child in the first position to give one of 21 Valentine’s cards anti-clockwise to the person next to their neighbour then the child to receive a card at last will be the third child. As there are 21 cards and they'll pass it one left one. So, in 7 rounds all the cards'll finish. And dividing 21/7 we get 3.
