If the total number of feet be 224 more than the number of heads, find the number of keepers.2) In a family, the father took 1/4 of the cake and he had 3 times as much as each of the other members had. The total number of family members are? |

Answer» 1)Let the number of keepers be x. Then, total number of feet = 2*50+4*45+4*8+2x = 2x + 312 Total number of heads = 50+45+8+x = 103 + x Now, (2x+312) = (103+x)+224 => x = 15 2)Let the family members b x. Father ate 1/4 of the cake; Rest members GOT 3/4X, the father had 3 times more than other members share i.e 3/4, Now, 3(3/4x) = 1/4, 3/4x = 1/12, 36 = 4x, X = 9, 9 + 1(father) = 10 total family member. |
