pls answer this refrigeration Engineering problem ?

Mass of ice at -4°C is needed to cool 115 kg of vegetables in a bunker for 24 hours. The initial temperature of vegetables is

assumed to be 30°C. It is also assumed that the average temperature inside the bunker is 7°C within 24 hour period. If the

heat gained per hour in the bunker is 30% of the heat removed to cool the vegetable from 30°C to 7°C, what would be the

required mass of ice? Specific heat of vegetable = 3.35 kJ/kg·K
