Little Mammu and the Marbles

           Little Mammu was playing marbles with her friend Nawal I heard her say to him, ‘if you give me one of your marbles I’ll have as many as you.’ Nawal replied, if you give me one of your marbles, and I’ll have twice as many as you.

          I wondered how many marbles each had! What do you think? 

Answer: Mammu had 5 marbles and Nawal 7
