| Profit on 1st part Profit on 2nd part | ||
| 8% | Mean Profit 14% | 18% |
| 4 | 6 | |

Ql=Quality of Lower.
Qh=Quality of Higher(Let x).
Pl=Profit of Lower.
Ph=Profit of Higher.
Ql/Qh=(Ph - M)/(M - Pl).
(1000-x)/x=(18-14)/(14-8).
(1000-x)/x=4/6.
(1000-x)/x=2/3.
2x=3000-3x.
5x=3000.
x=600.
Qh=Quality of Higher(Let x).
Pl=Profit of Lower.
Ph=Profit of Higher.
Ql/Qh=(Ph - M)/(M - Pl).
(1000-x)/x=(18-14)/(14-8).
(1000-x)/x=4/6.
(1000-x)/x=2/3.
2x=3000-3x.
5x=3000.
x=600.

Let us consider 2 part X(18%)&Y(8%).
Now 1000-x = y.
1000*1.14 = x*1.18+y*1.08.
1000*1.14 = x*1.18+(1000-x)1.08.
1000*0.06 = x*0.1.
x = 600.
Now 1000-x = y.
1000*1.14 = x*1.18+y*1.08.
1000*1.14 = x*1.18+(1000-x)1.08.
1000*0.06 = x*0.1.
x = 600.
