Question:A group of 266 persons consists of men,women and children. There are four times as many men as children. And twice as many women as children. How many of each are there.
Answer:
38×1=38 children
38×2=76 women
38×4=152 men
Solved With Ratios
M ÷ C = 4 ÷ 1
W ÷ C = 2 ÷ 1
Conclusion: M ÷ W ÷ C = 4 ÷ 2 ÷ 1
The sum of the ratios is 4 + 2 + 1 = 7 which means we can divide the total number into 266 ÷ 7 = 38 groups, each group having 1 child, 2 women and 4 men.
