A tap supplies water at 10degree Celsius and another tap at 100degree Celsius. How much hot water must be taken so that we get 20kg water at 35degree Celsius? A-7.2kg,b-10kg,c-5.6kg,d-19.9kg

If  m1 kg of hot water and m2 kg of cold water are mixed to get 20kg water at 35ºC 

The amount of heat released by the hot water by cooling =The amount of heat absorbed by the cold water to get heated

m1 x s (100ºC-35ºC) = mx s (10ºC-35ºC)

m1 = (m2 x 25) /65

but m+m2 = 20
