The restaurant can offer a platter with 1Cheese,1Fruit OR 2Cheese,2Fruits

1Cheese,1Fruit = 6C1*2C1
2Cheese,2Fruit = 6C2*2C2

Total number of platters restaurant can offer = 6C1*2C1 + 6C2*2C2 = 6*2 + 15*1 = 27
So It Goes

Givemeanid,

Can you explain how to compute the 6C1, 6C2. I completely forgot how to compute those. And when is it necessary to use them?

nCk = n! / (k! * (n-k)!)
nPk = n! / (n-k)!
