  1. Heat lost = Heat gained
    Let x be the final temperature of the mixture.

    (100)(60 - x)(4.184)=(200)(x - 30)(4.184)
    Solve for x

  2. Temp in mixture =M1t1+m2t2/m1+m2
    100*60+200*30/100+200=
    6000+6000 /300=
    12000/300=
    40
    Hence,40 is the temperature in mixture.
    Hope this helps you.
