24 oz of juice P and 25 oz of juice Q are mixed to make smothies X and Y . The ratio of p to Q in smothie X is 4 is to 1 and that in Y is 1is to 5.How many ounces of juice P are contained in the smothie X?	Choose the correct choice
A) 5  B) 10  C) 15  D) 20  E) 25

Rationale: easy way to solve this question is start from the answer and then conform the information provided in the question . we can start from option d i . e 20 . . . as a quantity of juice p in x because it is the only one option that gets divided by 4 is 20 . . . since in the x the juice p to q ratio is 4 : 1 this gives us that quantity of juice p in x = 20 therefore quantity of juice v will be 5 . . . hence ratio = 4 : 1 this will lead to quantity of juice p in x = 4 and quantity of juice v = 20 . . . hence ratio 1 : 5 if we calculate total juice p = 24 and total of juice q = 25 it fits because totals are same as what mentioned in the question . . . thus ans is d
Answer: D
