Question

Three liquids A, B and C having same specific heat and mass m, $$2m$$ and $$3m$$ have temperature $$200C$$, $$400C$$ and $$600C$$ respectively. Temperature of the mixture whenNow, match the given columns and select the correct option from the codes given below.Codes

When A and B are mixed            $$ms(T-20)$$ $$=$$ (2m) s (40-T) ⇒ T $$=$$ $$33.30CWhen$$ A and C are mixed           $$ms(T-20)$$ $$=$$ (3m) $$s(60-T)$$ ⇒ T $$=$$ $$500CWhen$$ B and C are mixed           (2m) $$s(T-40)$$ $$=$$ (3m)s(60-T) ⇒ T $$=$$ $$520CWhen$$ A, B and C are mixed          $$ms(T-20)$$ $$+$$ (2m)s(T-40) $$=$$ (3m)s(60-T)⇒ T $$=$$ $$46.670C$$
