张静买3公斤苹果,梨2公斤共付12元,王海买同样价格的3公斤苹果,梨5公斤共付21元,问苹果和梨各是多少元

设张静得x分,则李东得（x+64）分
x+(x+64)=208
2x=144
x=72
x+64=136
设张静做对x题,则她做错（10-x)题
20x+(-12)(10-x)=72
32x=72+120
x=6
10-x=4
设李东做对y题,则他做错（10-y）题
20y+(-12)(10-y)=136
32y=136+120
y=8
10-y=2
答：张静做对6题,做错4题；
李东做对8题,做错2题.

Dear Emma,
I heard you are going to have a trip .Now let me tell you what I think of trip.Trip is a good activity,and it's good for our health.But it always has many problems.For example,changeable weather and it's easy to be ill.I think if you are going to have a trip to somewhere,you should know the weather of there and look after your belongings.
I hope you have a good trip!
Yours,
Zhangjing
