I am getting a large equation...
It takes Bhuvan, Bheem and Bahadur 18,24 and 36 days respectively to do a piece of work. Each of them does the same amount of work and they complete the work in 26 days. Instead, if Bheem did extra work equal to the sum of yth parts of the works done by Bhuvan and Bahadur, they could have completed the work one day earlier. How much more work did Bheem do in the 2nd case as compared to that done by him in the 1st case?
a) 1/9
b) 1/6
c) 1/4
d) 1/3
Can someone give a detailed solution to this?

The percentage volumes of alcohol in three solutions S1, S2 and S3 form a geometric progression in that order. If we mix the first, second and third solutions in the volume ratio 2 : 3 : 4, we obtain a solution containing 32% alcohol. If we mix them in the ratio 3 : 2 : 1, by volume, we obtain a solution containing 22% alcohol. What is the percentage of alcohol in S1?

A dog chases a cat and takes 5 leaps for every 6 leaps of cat, but 4 leaps of dog is equal to 5 leaps of cat. Compare the speeds of dog and cat?
(What I am thinking is leap frequency(time ratio) is 5:6 and leap distance(distance) ratio is 4:5. Therefore speed ratio will be 4/5:5/6, that is 24:25 but answer is reverse of it that is 25:24) Where am I wrong? Please guide?
- 24:25
- 25:24
