Wow that's a great mixture
I went to a party last night. There were two barrels of wine one filled with grape wine and one with orange wine. I thought to do an experiment, I took a wine glass and filled it half with grape wine and orange wine in the ratio 9:4, rest half of the glass I filled with water. Now I drank 40% of it and again filled grape wine and orange wine in ratio 6:7.
Now what is the percentage of grape wine in the resulting mixture?
