Nazim is planning to cook curries and sell them. He will take orders for parties. He will cook the curry and rice beforehand, then put the cooked food in serving dishes that will keep it hot. Nazim will pay his friend Raj, who has a van, to make deliveries and to fetch the serving dishes back after the party. Nazim’s first order is for a party of 27 people. He has a recipe using vegetables, chick peas, onions and tomatoes. He is now trying to work out the right quantities of spices. For 15 people he would normally use 100 g of spices, made up of ginger (20%), turmeric (25%), coriander (35%), and cumin seeds (20%). What weight of turmeric must Nazim put in a curry for 27 people?
