Are You Up For the Challenge: 700 Level Questions: 700 Level QuestionsLet the price of one 48-ounce container of ice cream X be x and price of one 64-ounce container of ice cream Y be y
We have to find y
Statement 1 - A customer at Mimi’s bought one 64-ounce container of Brand Y ice cream and two 48-ounce containers of Brand X ice cream for $15
2x + y = 15 - (i)
Insufficient
Statement 2 - A customer at Mimi’s bought a total of 192 ounces of ice cream for $18
A customer could either have bought 4 48-ounce container of ice cream X or 3 64-ounce container of ice cream Y
The customer can't buy any container in fractions.
So one 48-ounce container of ice cream X costs $4.5 or one 64-ounce container of ice cream Y costs $6
We are not sure for value of y
Insufficient
Combining both,
If we put value of x in eqn (i), we get y = 6
So, we are now sure that the value of y is 6
Sufficient
