Here I am with a question....
A certain ice cream company is coming out with a new flavor, Almond-Pecan-Chip, and the recepie for which includes almonds, pecans and chocolate chips in a 7:4:2 ratio. If each gallon of ice cream contains a total of 182 pieces of almond, pecans and chocolates chips what is the difference between the number of almonds and the number of chocolate chips in one gallon of ice cream?
a) 98
b) 70
c) 64
d) 42
e) 28
I go for A, but I am not sure.....can somebody can provide some explain. Thanks,

ratio is 7:4:2

7x + 4x + 2x=182

13x=182

x=14

no of almonds=7x=7*14=98

no of choc chips=2x=2*14=28

difference=98-28=70

Hence it is B

A = 7X,P = 4X,ch=2X

13X=182, X = 14

7X-2X = 5X = 14*5 = 70....B
