Question

In a cookie mix, we find almond cookies, molasses cookies, and cinnamon cookies in a
ratio of 1 : 7 : 2. If a bag of the mix contains 119 molasses cookies, how many cookies in
total are there?

Answer 1

Ratio of almond cookies:molasses cookies:cinnamon cookies= 1:7:2
Let total no. of cookies be= 1x+7x+2x= 10x
Molasses cookies=119
=> 7x=119
=>x=119/7
      =17
Total no. of cookies= 10x
(x=17)
10x=10 x 17
=170
Thus, total no. of cookies= 170



Hope it helps ;D
