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
