According to the meaning of the topic, slowly clear your mind. It can be seen from the first and second sentences that 1/3 peaches and 12 olives can be bought at 1/3 cents, that is, 1/3 X= 12. Similarly, 1/4 z = 65438.
In addition, x+y+z =100; 3X+ 1/ 12Y+4Z = 100； Through the calculation of three equations, the final conclusion is drawn:
There are X= 18 peaches, 72 peaches and Z= 10 peaches.
