A and B have a certain number of chocolates with them. If B gives one chocolate to A, they will have equal number of chocolates. But if A gives one chocolate to B, then A will be left with half the number of chocolates that B has.
Can you find out the number of chocolates they have right now?
Let us say that A has P no. of chocolates and B has Q no. of chocolates right now.
Now according to the question:
P + 1 = Q - 1
=> Q - P = 2 ------ (i)
Also, P - 1 = (Q + 1) / 2
=> 2P - Q = 3 ------ (ii)
Equating (i) and (ii)
P = 5 and Q = 7
Therefore, A has 5 chocolates and B has 7 chocolates right now.
