Q. If the heat transfer efficiency is 0.5 and the melting efficiency is 0.6, then the overall efficiency will be?

(A) 0.83
(B) 0.03
(C) 0.30
(D) 0.12
Correct : Option (C)

Explanation: 
 ηtotal = ηmelting * ηheat transfer, where η denotes efficiency. there are two types of efficiencies, one is melting efficiency and another is heat transfer efficiency.
