Questions flaw?
Normally the working...
Total money = 25× 60 = 1500u
1 pen = 1500u÷ 25 = 60u
1 ruler = 1500u ÷ 60 =25u
Assumed all are ruler,, total money = 51×25u= 1275u
Shortfall = 1500u-1275u = 225u
The price difference of 1pen and 1ruler= 60u-25u = 35u
Therefore, total pen = 225u÷35u = 6.42857429 ?(pen can't be 6.4....)
Ruler will be 51-6.42857429=44.57142857 ：)
So she bought 6 pens and 45 rulers with some money remaining.
