Dear saurabh


let  c1 ,c2,c3 are the heat capacity of  liquid a,b,c


when a and b are mixed.


mc1*10  + mc2*15 =mc1* 12 + mc2*12


 3c2 =  2c1.............1


 


when b and c are mixed.


mc2*15  + mc3*25 =mc2* 21 + mc3*21


 2c3 =  3c2.............2


from equation 1 and 2


c1=c3


now liquid a and c are mixed  let the final temperature is T


mc1*10 + mc3*25 = mc1*T + mc3*T


 T = 17.5
