170kg*Rs.5.80=Rs.986.
130kg*Rs.5.30=Rs.689.
Total C.P=Rs.986+Rs.689=Rs.1675.
Gain= Rs.161.
S.P=C.P+Gain.
=Rs.1675+Rs.161.
=Rs.1736.

The rate of the mixture let kg=(1736/300)=Rs.5.786.

Add 25% of 576, i.e 144.

I would like to know whether gain calculated on CP or SP?

25% is the right answer.

Simple logic.

If the c.p of 20 articles is = 20rupees,
So 20=100%.

The s.p of x articles is = 20rupees,
if gain% is 25% it means 20 rupees of c.p is = 125%.
We need to understand that 5 is 25% of 20.

So 100%+25%=20+5,
125%=25.

Now we can find the s.p of 1 articles
s.p 25÷20 c.p =1.25.

The s.p of 1 articles is =1.25.
Now we can find the sold (x) articles those make 20 rupees
20÷1.25=16.

Sold articles is =16 Ans,
And.
20*1.25=25,
25 = 125% of c.p 20.

If the c.p of 20 articles is=20rupees.
So 20=100%.
The s.p of x articles is=20rupees,
If gain% is 25% it means 20 rupees of c.p is= 125%.
We need to understand that 5 is 25% of 20.
so 100%+25%=20+5,
125%=25.

Now we can find the s.p of 1 articles,
s.p 25÷20 c.p =1.25
The s.p of 1 articles is =1.25.

Now we can find the sold (x) articles those make 20 rupees,
20÷1.25=16.

Sold articles is =16 Ans.
And
20*1.25=25,
25=125% of c.p 20.

How is divided [300*100]/5500?

I don't understand, please explain in detail.

How can we find cost price, if selling price and profit percentage is given?

Formula for gain % is,
Gain = Selling Price(SP) - Cost Price(CP).

Gain% = (Gain/C.P)*100.
Then why the gain is divided by SP in the answer?
