Hiro's Grocery Shopping

Hiro went to the store after school to pick up one jug of milk, one loaf of bread, one dozen eggs and one package of cookies. Milk comes in 1%, 2% and 3.25% varieties. Bread comes in white and 100% whole wheat. Eggs come in dozen-pack of various sized: small, medium, large and jumbo. Cookies come in three different flavours. How many different ways can Hiro bring home the items from his list?

We just need to multiply the varieties with each other (according to my theory we can find a suitable common multiple by doing this)... i m just taking varieties as a,b,c,d.. & so on.. Milk- a,b,c (3) Bread- d,e (2) Eggs- f,g , h,i (4) Cookies- j, k ,l (3)

so, 3x2x4x3 = 72 so 72 is the answer...!!
