Call the amount that Mahmud has              X      

And call the amount that Rihan has is        4 • 1/5 • X    

 

Together, they have                                    756

 

Add M's & R's together to equal                  X + ( 4 • 1/5 • X )  =  756

 

4 • 1/5 • X = 4X/5

1 • X          = 5X/5

                                                                    4X/5 + 5X/5  =  9X/5  =  756      

Multiply both sides by 5                                                           9X  =  3,780     

Divide both sides by 9                                                               X  =  420        

 

Mahmoud has 420
