A cat takes 5 leaps for every 4 leaps of a dog, but 3 leaps of the dog are equal to 4 leaps of the cat. What is the ratio of the speed of the cat to that of the dog?
1. 13 : 14
2. 15 : 11
3. 17 : 15
4. 15 : 16

• Option 4 15:16
  Let the leap of dog is x and leap of cat is y
  then 3x=4y and 5y=4x
  y=4x/5
  solving this we get 15:16

• y=4*4y/3*5

• This question is wrong. None of these ans is correct.

  how we can solve here?

  y=4*4y/3*5

  same here? How could we solve this?

• 4 leaps of cat = 3 leaps of dog
  
  ⇒ 1 leap of cat = 3/4 leap of dog
  
  Cat takes 5 leaps for every 4 leaps of dog.
  
  So the required ratio is (5× Cat′s leap) : (4 X Dog's leap)
  
  = (5 × 3/4 dog′s leap) : (4 X Dog's leap)
  
  = 15 : 16
