Whoever solves is a genius! chris visited the local pizza shack to purchase one pizza for each member of his scout troop. on arrival, he realised that he had mislaid the list he had made of the pizzas that had been requested. he knew that there were 32 people altogether and that all 3 vegetarians in the troop wanted mushrooms only. he also remembered that the same number of people wanted just the chicken topping as wanted a plain pizza. alex, a young leader, was able to by recalling that: 12 people requested toppings that included chicken, 10 requested toppings that included pepperoni, 9 requested toppings that included mushroom, 1 person wanted all 3 toppings, 2 wanted chicken and pepperoni only, 2 wanted peperoni and mushroom only. what was the final order that chris placed at pizza shack?
