| 4 | 6 | |
Ration of 1st and 2nd parts = 4 : 6 = 2 : 3
Quantity of 2nd kind = |

14-8 = 6.
18-14 = 4.
Ratio of 1st = 2:3.
Now;
2+3 = 5,
5 units = 1000,
1 units = 200, then
3 units = 3*200 = 600.
18-14 = 4.
Ratio of 1st = 2:3.
Now;
2+3 = 5,
5 units = 1000,
1 units = 200, then
3 units = 3*200 = 600.

Let x part is sell with 8% profit
And the rest 1000-x with 18%
And total profit is 14%.
Then we can write;
(X * 8) (1000-x)*18 (1000 * 14)
---------------- + ----------- = ------------------
100 100 100
Here all 100 in the denominator is cancel out;
And we get,
8x + 1000*18 - 18x = 1000*14
-10x = 14000 - 18000
-10x = -4000
X = 400.
The quantity sold at 18% profit is:
1000 - x = 1000 - 400 = 600 Ans.
I HOPE IT WILL HELP TO MAKE WITH BASIC WITHOUT ALLIGATION METHOD.
THANK YOU.

8x + 18(1000-x)/x+1000-x =14.
8x+18000-18x = 14000,
Solving x you get 400,
1000 - 400 = 600.
8x+18000-18x = 14000,
Solving x you get 400,
1000 - 400 = 600.

118x + 108(1000 - x) = 114000.
59x + 54(1000 - x) = 57000.
5x = 3000.
x = 600.
59x + 54(1000 - x) = 57000.
5x = 3000.
x = 600.

@Aditya.
Just like the above question we can apply same rule and method to solve your question.
ANSWER:
He sold 30kg sugar for 18% profit.
After solving we get 4:6=>2:3
3/5*50 = 30.
Here 30 indicates kgs.
