ANSWER:

You have to segregate the two transactions as buying and selling gold must be hand to hand. He can sell his 20gm of gold to you and you must give him the value in cash in his hand. Once he receives the money, he can then, if he wishes, buy any new gold from you or from anyone else. 

Sheikh, if anyone comes to my gold shop and sells me 20 gm of old gold and want 20gm of new gold is this permissible , if any person comes and wants to sell his 20gm of old gold and want to buy 25gm of new gold what can i do,can i give him first 20gm of gold and then 5gm gold with cash,what is the solution?
