Ekta can go to shop in different 5 days from tuesday to saturday . Similarly Shyam also go to in different 5 days . There fore when one action is done in n different ways, and for each of n ways another action can be done in m ways, the total no. of actions ( or ways) is n×m . Here n=5, m=5 . So total no. of ways is 5×5=25 . Hope you understand Mr. Ajay .
