Let A be the tea that sells 240 pesos per kilo and Let B be the tea which sells 200 pesos per kilo. The amount taken from A is x and amount taken from B is y. Then,

Total amount = `150 = x+y`

Selling price of 150 kg `= 220(150) = 240x+200y`

Thereforem `220(150) = 240x+200y`

Dividing by 40,

`825 = 6x+5y`

Now e have two simultaneous equations for x and y, we can solve theme to fins values for x and y.

x = 75 and y =75.

**The amount needed from each type are, 75 kg from A and 75 kg from B.**

Now let us check our answer.

Cost of 150 kg of mixture = 75(240)+75(200)

= 33000

Cost of 1 kg of mixture = 33000/150

= 220.

Therefore our answer is correct.
