Answer:
40,000
Explanation:
The calorific value of fuel is the amount of heat produced by the complete combustion of 1 kg of fuel.
Heat produced by 4.5 kg of fuel =180000 kJ.
Heat produced by 1 kg fuel =
4.5
180000
=40000 kJ/kg.
Hence, the calorific value of the fuel is 40,000 kJ/kg.

Answer:
1kJ is 0.239 kcal
calorific value of A=energy from 1 kg fuel A =20000/5=4000×0.239k cal
similarly
calorific value of B =30,000kJ/4=7500×0.239 kcal
