A Man Has Some Hens And Cows. If The Number Of Heads Be 48 And The Number Of Feet Equals 140, Then The Number Of Hens Will Be? |
|
Answer» LET the number of HENS be x and the number of cows be y. Then, x + y = 48 .... (i) and 2x + 4Y = 140 x + 2y = 70 .... (II) Solving (i) and (ii) we get: x = 26, y = 22. The required answer = 26. Let the number of hens be x and the number of cows be y. Then, x + y = 48 .... (i) and 2x + 4y = 140 x + 2y = 70 .... (ii) Solving (i) and (ii) we get: x = 26, y = 22.
