There are 2 stables with horses in both of them,there are 20 more horses in the 1st one than in the 2nd one. If 8 more horses arrives to the first stable and 2

Question

more horses arrive  the second stable , there will be 3 times more horses in the first stable than in the second one. How many horses are there in the two stables now? 

Answer 1

let x = number of horses in first stable now ---> x = y + 20 now ---> later, there will be x + 8 = y + 28 horses in stable 1

 

let y = number of horses in second stable now ---> later, there will be  y + 2 horses in stable 2

 

thus, y + 28 = 3(y + 2) ---> y + 28 = 3y + 6 ---> 2y = 22 ---> y = 11;  and x = y + 20 = 11 + 20 = 31
