I can't solve this Math riddle from our textbook at school, we never answere!
Question: Professor Sam poured "The Secret Formula" into a glass until it was one-half full. Then he poured "The Secret Formula" into a second glass until it was one-fourth full. The second glass was twice as large as the first glass. Both glasses were then filled with water.
That afternoon, the absent-minded lab assistant mixed the contents of both glasses in the third container.
The question is "The Secret Formula" is what part of the final mixture?

The question is "The Secret Formula" is what part of the final mixture?
Let the capacity of the first glass be x units.
So, of the second glass it is 2x units.
The secret formula in first glass=(x/2) units
The secret formula in second glass=(2x/4) units=(x/2) units
Total volume of secret formula=x units
Total volume of solution=(x+2x)units=3x units
HENCE THE SECRET FORMULA IS ONE-THIRD OF THE FINAL MIXTURE(33.33%)
i got 1/2 not 100% sure but i think it is. like 99.9%
hope its right
3parts secret formula to 5 parts water
i think
nah it is 1/2
put it into A)50ml container and B)100ml container
A) 25ml formula + 25ml water
B) 25ml formula + 75ml water
= 50ml formula + 100ml water
the final mixture has a ratio of 1 part formula to 2 parts water
1/3..xx..?
3/4 parts is secret formula and 5/4 parts is water...........................
This is a cool riddle, I'll try to answer. If the second glass was twice the size of the first then both glass would contain the exact amount. The formula will make up one-third of the entire mixture.
Let the first glass be 8 oz. Fill half = 4 oz formula
Let the second glass be 16oz. Fill quarter = 4oz formula
Total capacity of both glasses = 24oz
Total amount formula = 8oz
To find the fraction of 24oz(total glass capacity) devide 24 by 8 = a third
yes pink bear. 1/3
1/3
Maybe drawing it out would help it make sense.
"The Secret Formula"? He emphasizes on this.The answerer is 1/4.It is a trick question .He never did say another cup.In other word he took the 1/2 amount of fluid in a two times smaller cup and poured it into a cup that was 2 times bigger .That would automatically reduce it by half.Which would bring it to 1/4.I used to love this in school,because you can not just base on Numbers you also have to make sure that you read and really understand the question.It is like playing on words only put together with math. I have to admit that i did try to figure all kinds of other ways of math Equations for an hour or so ,i think,and finely realized that it was a trick question.
1st glass=half, second glass=2 x 1/4=1/2
after mixed together, water =1/2 + 1/2 =1
secret formula=1/2 +1/2 =1
ans: secret formula +water=final mixture=1+ 1=2
secret fomula is to final mixture is 1 parts is to 2 parts.
