A number of girls bought red, green and black ball pens. Three bought one of
each colour. Of the girls who bought two colours: 3 did not buy red, 5 not green
and not black. The same number of girls bought red only as bought red with
other colours. The same number bought black only as bought green only. More
girls bought red and black but not green than bought black only, but more giris
bought green only than green and black but not red.
D). Represent this information on a Venn diagram.
10). How many girls were there?

31 girls

Explanation:

The way this question is worded, one can see that one will likely be able to calculate the number who bought pens of all three colors, the number who bought pens of only two colors and the number who bought pens of only one color.

The total number of girls will equal the following.

The Number Who Bought Only One Color + The Number Who Bought Only Two Colors + The Number Who Bought All Three Colors

Let's break down what the question says to get some subtotals.

Three bought one of each colour.

-- 3 Bought All Three

Of the girls who bought two colours, 3 did not buy red, 5 not green and 2 not black.

-- 3 Bought Only Black And Green

-- 5 Bought Only Black And Red

-- 2 Who Bought Only Red And Green

The same number of girls bought red only as bought red with other colours.

I guess this means the following.

-- 3 Bought All Three

-- 5 Bought Red And Black

-- 2 Bought Red And Green

-- 3 + 5 + 2 = 10 Bought Only Red

More girls bought red and black but not green than bought black only,

-- < 5 Bought Only Black

more girls bought green only than bought green and black but not red.

-- > 3 Bought Only Green

The same number bought black only as bought green only.

-- 3 < Only Green = Only Black < 5

-- 4 Bought Only Green

-- 4 Bought Only Black

Total:

3 All Three

3 Only Black And Green

5 Only Black And Red

2 Only Red And Green

10 Only Red

4 Only Green

4 Only Black

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
