Let the parts be x & (1000-x) kgs sold at selling price of S1(@8% profit) & S2(@18% profit) respectively.
Assuming that the cost price per kg of sugar is constant for both transactions, we have:
(S1-x)/x =0.08
[S2-(1000-x)]/(1000-x) =0.18
Also, ts given that total profit is 14%. So,
[(S1+S2)-1000]/1000 =0.14
We need to find value of (1000-x) i.e the quantity sold @18% profit. Substitute S1,S2 in terms of x in the above eqn. We get: x=400. Thus, (1000-x)=1000-400=600 kgs
