Because they have asked only about the quantity which is sold for 18% profit
if they asked to fine out the quantity which is sold for 8% profit you can multiply 2/5 (bcs 2/(3+2)) with 1000.

=(2/5) * 1000 => 400kg.

A businessman sells some sugar in total sugar of 50 kg on 8% profit and remaining sugar on 18% profit. If the average profit is 14%. Find the amount of sugar which was sold on 18% profit.

Can anyone solve this?

Thank you all.

@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.

Thank you all for explaining the solution.

Clear explanations. Thanks for your great help.

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.
