Step-by-step explanation:

We have given, A survey of 290 newspaper readers.

Who read the Daily times A=181

Who read the Guardian times B=142

Who read the punch C=117

Who read Daily Times and the Guardian A\cap B= 75

Who read Daily Times and the punch A\cap C=60

Who read Guardian and punch B\cap C=54

To find :

How many readers read All three papers, Exactly two of the papers The Guardian alone?

Solution :

Readers read all three papers is $A\cap B\cap C$

Total survey is given by,

Total = $A+B + C- A\cap B- A\cap C - B\cap C+ A\cap B\cap C$

290 = $181 + 142 + 117 - 75 -60 - 54 +A\cap B\cap C$

290 = $251+A\cap B\cap C$

290-251= $A\cap B\cap C$

$A\cap B\cap C=39$

So, number of readers who read all three papers is 39.

Exactly two of the papers = 36 + 21 + 15 = 72

It is 1 1/4 miles from Ahmed’s house to school. How far does Ahmed’s travel in 5 days walking to school and back

Sauron [17]

Ahmed travel $12\frac{1}{2}$ miles in 5 days walking to school and back.

Step-by-step explanation:

Distance from house to school = $1\frac{1}{4}$ miles

Distance from school to house = $1\frac{1}{4}$ miles

Total distance in 1 day = $1\frac{1}{4}+1\frac{1}{4}=\frac{5}{4}+\frac{5}{4}$

Total distance in 1 day = $\frac{5+5}{4}=\frac{10}{4}$

Distance traveled in 5 days = $5*\frac{10}{4}=\frac{50}{4}$

Distance traveled in 5 days = $\frac{25}{2}=12\frac{1}{2}$

Ahmed travel $12\frac{1}{2}$ miles in 5 days walking to school and back.
