If Pei ordered a total of 63 bottles of Cola, Root Beer and Ginger Ale for a part. How many Cola bottles did she order?

Given: {Cola} + {Beer} + {Ale} = 63.
Question: {Cola} = ?

(1) The no of bottles of root beer Pei order was 80% of bottles of ginger ale that she ordered --> {Beer} = 0.8{Ale} --> 5*{Beer} = 4*{Ale} ({Beer} is a multiple of 4 and {Ale} is a multiple of 5). If {Beer} = 4 and {Ale} = 5, then {Cola} = 54 but if {Beer} = 8 and {Ale} = 10, then {Cola} = 45. Not sufficient.

(2) The no of bottles of cola Pei order was 75% of total no. of bottles of ginger ale and root beer that she ordered --> {Cola} = 0.75*({Beer} + {Ale}) --> {Beer} + {Ale} = 4/3*{Cola} --> {Cola} + 4/3*{Cola} = 63. We can solve for C. Sufficient.

Answer: B.

Answer: B.


Question : How did you get from 0.8 Ale to 5 Beer , and then to the 4 ale, beer ? Also, how did you get from 0,75 beer ale to 4/3 cola?

Hi sagnik242,

let me try to help.
Beer = 0.8 Ale
Beer = \(\frac{8}{10}\) Ale
10 Beer = 8 Ale (multiply the entire expression with 10)
5 Beer = 4 Ale (simplify by dividing the entire expression with 2)

same goes with 0,75 beer ale to 4/3 cola. hope that was helpful :D

This question could be very tricky if total number of bottles bought was between 10 and 17. A could be sufficient.


When I solved A, I didn't use any equation. I tried to think logically that Number of cola bottle could be any number if I different number of Ginger ale bottles.

But after looking the official solution, I realized that my thought process for A could be dangerous. I have to actually form equation in this type of situation.
