Answer 2

Answer:

200 ml.

Step-by-step explanation:

Given,

The temperature of the mixture is at 70 degrees Celsius. One liquid of the mixture is at 90 degrees Celsius and 100 ml of it is in the mixture and the second liquid is at 60 degree Celsius.

Let the quantity of second mixture be x.

A.T.P.

100*90+60*x=70*x+100

Or,9000+60x=70x+7000

Or,9000-7000=70x-60x

Or, 2000=10x

Or, 2000/10=x

Or, 200=x

Or, x=200
