The table shows, for four newspapers W, X, Y and Z, the number of copies printed and the number distributed across four cities in a day.

Newspaper	Printed	City 1	City 2	City 3	City 4
W	500	1500	1000	500	500
X	10000	3000	3500	1500	1000
Y	10000	35000	3000	1500	500
Z	50000	1000	1000	500	1500

What is the ratio between the total number of distributed copies of Newspaper W and the total number of distributed copies of Newspaper Z?

A7:8 ✓ Correct

B8:9

C4:7

D4:5

Correct answer: (A) 7:8

Explanation

The ratio is 7 to 8, so the answer is 7 to 8.

Newspaper W is distributed as 1500, 1000, 500 and 500 across the four cities.

So the total for W is 1500 plus 1000 plus 500 plus 500, which is 3500.

Newspaper Z is distributed as 1000, 1000, 500 and 1500.

So the total for Z is 1000 plus 1000 plus 500 plus 1500, which is 4000.

The ratio of W to Z is therefore 3500 to 4000.

Dividing both by 500 gives 7 to 8.
