Hi,

Since A = B = 5 litres

24=$$\frac{\left(5x\ +\ 5\left(x+8\right)\right)}{5+5}$$

On solving x =20

Hope this helps.

Hi. Actually, amount here does not mean the amount of money but the amount of mixture present. A here refers to the litres of mixture A present and B refers to the litres of mixture B present in 10 litres. x+8 and x represent their cost prices respectively. Hope this is clear.

Hi Ridu Varshini,

The mixture contains both A and B, and the mixture costs Rs 24.

If you take the cost of A as Rs 24 and the cost of B as Rs 16, then the cost of the mixture will be between 16 and 24 as we are mixing both A and B. 

If we take A is 28 and B is 20, and we mix them in equal quantities, the cost of the mixture will be Rs. 24.

I hope this helps.

Hi Adharsh,

We have the equation,
(10 - B) * (X + 8) + BX = 240
10X + 80 - BX - 8B + BX = 240
10X - 8B + 80 = 240
taking 8B and 80 to the RHS, we get,
10X = 240 - 80 + 8B
10X = 160 + 8B
Dividing the equation by 10, we get,

$$\dfrac{10X}{10}\ =\ \dfrac{\left(160\ +\ 8B\right)}{10}$$

$$X\ =\ \dfrac{\ 160\ }{10}\ +\ \dfrac{8B}{10}$$

$$X\ =\ \ 16\ +\ \dfrac{4B}{5}$$

Hope this helps!
