Solution Y is 30 percent liquid X and 70 percent water. If 2 kilograms of water evaporate from 8 kilograms of solution Y and 2 kilograms of solution Y are added to the remaining 6 kilograms of liquid, what percent of this new solution is liquid X?

Read Solution (Total 2)

8 kg of solution Y contains 5.6 kg of water and 2.4 kg of liquid X.
2 kg of solution Y contains 1.4 kg of water and 0.6 kg of liquid X.

1. After evaporationg the rest 6.0 kg of solution contains 3.6 kg of water and 2.4 kg of water.
2. 8.0 kg of mixed solutins 5.0 kg of water and 3.0 kg of liquid X.
So percent of liquid X in new solutin is 3.0 / 8.0 * 100 = 37.5 %

ANSWER : 3kg

SOLUTION:

8 kg of solution Y contains 5.6 kg of water and 2.4 kg of liquid X.
2 kg of solution Y contains 1.4 kg of water and 0.6 kg of liquid X.
AFTER evaporation
6 kg of solution Y contains 3.6 kg of water and 2.4 kg of liquid X.
SINCE NO EVAPORATION TAKE PLACE IN LIQUID 'X'
So, Total liquid x is 2.4 kg + .6 kg = 3 kg

In China of the tang dynasty unprecedented social kiosks prevailed but yet there was a great mathematician and quote astronomer who reveled in numerical riddles. In his compilation of such puzzles the total numbers of puzzles is equal to the product of the number of the puzzles that classified as easy and extremely difficult. Now if 1/2 of the numbers is 2 more than 1/6 of the same number. What is the number in the binary system? Archi was the son of the Nymph Thetis and Peleus, king of Myrmidons. Zeous and Poseidon had been rivals for the hand Thetis until from Prometheus, the fire bringer warned Zeous of a prophecy that Thetis would bear a son greater than his father. For this reason the 2 Gods withdrew their pursuit and had her wet Peleus. The following statement is another interesting prophecy about the ages of 2 children of Zeous that would hold true at some time during the life time of the children. 3 years ago Ethina's age was twice Hellena's age. 3 years hence Ethina's age will be 4/3 times the age of Hellena. Find Ethina's present age in binary numbers during the time that statements hold true?
