In a group of cows and chickes, the number of legs was 14 more than twice the number of heads . the number of cows was:  Choose the correct option:
A) 7	B) 5	C) 11	D) 12	E) 14
no of cows x and their legs 4x, no of chicke y and their legs 2y, total no of legs= 4x + 2y, total nof heads = x + y, the no of legs was 14 mor than twice the number of heads. 2x + 2y +14 = 4x + 2y, 14= 4x-2x+ 2y -2y, therefore, 14 = 2x , x = 7, correct answer : (7)
