At a soccer ,match 60% of the spectator were men and rest are women and childre.
Answers
Answer:
s = 700
Step-by-step explanation:
We need a series of equations to be able to sub back and forth into one another in order to get this down to one variable, s for spectators. This is what we know from the info (in algebraic expression/equation form):
6s = men (60% of the spectators are men)
4s = women + children (40% of the spectators are women and children)
# of children = 2/3 women
# of men = women + 252 (There are 252 more men than women) and
# women = men - 252
Those are the equations we need to solve for the number of spectators.
Start at the top with
6s = men. We know that the number of men = women + 252, so
6s = women + 252.
4s = women + children. We know that the number of children is 2/3 the number of women, so
4s = women + 2/3 women. If the number of men = women + 252, then
4s = men - 252 + 2/3(men - 252) which simplifies to
4s = 3/3 men - 252 + 2/3 men - 168 and
4s = 5/3 men - 420 and
4s = s - 420 and
6s = -420 so
s = 700
Although your answer is incomplete, you may be referring to:
At a soccer match, 60% of the spectators are men and the rest are women and children. The number of children is 2/3 of the women. There are 252 more men than women at the soccer match. How many spectators are there altogether?
Given:
Percentage of men = 60%
Percentage of women and children = 40%
Number of children = the number of women
Number of men = 252 more than the number of women
To Find:
The total number of spectators
Let us assume:
Let the number of men be x
Let the number of women be y
Let the number of children be z
Let the total number of spectators be a
Solution:
- For solving this question, we need to make equations based on the given conditions.
Step 1: Find a relation between the number of women and children
- It is given that the number of children = the number of women
⇒ z = y
- We also know that the total number of women and children makes up 40% of the total number of spectators.
⇒ y + z = × a
⇒ y + y = a
⇒ =
⇒ y = (1)
Step 2. Find an expression for the relation between the number of men and women.
- We know that the number of men is 252 more than the number of women.
x = y + 252
⇒ x-y = 252
- We also know that the number of men makes up 60% of the total number of spectators.
⇒ x = × a
⇒ x = (2)
Step 3. Find the total number of spectators.
- From (1) and (2) we get:
x-y = 252 can be written as:
- = 252
⇒ = 252
⇒ = 252
⇒ a = 700
