Tapiwa raked %5, percent more leaves than adam raked. together, they raked 697 liters of leaves. how many liters of leaves did adam rake?

 If we assume that Adam raked x liters of the leaves then Tapiwa raked 105% of the  liters of leaves by Adam (1.05 x liters). But, we know that the total liters of leaves are 697.
                       Thus    x + 1.05 x = 697
                                  = 2.05 x = 697
                           thus x = 340
Thus Adam raked 340 liters of leaves while Tapiwa raked  357 liters 
Hence the number of liters by Adam as required in the question is 340 liters.
