What is the ratio of the total number of pages printed by printer P over the course of three days to the total number of pages printed by printer Q during the same three days?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 10 : 9.
The total number of pages printed by printer P in three days = 100 + 120 + 180 = 400
The total number of pages printed by printer Q in three days = 130 + 145 + 85 = 360
Required ratio = 400 : 360 = 10 : 9
Therefore, the ratio of the total number of pages printed by printer P over three days to the total number of pages printed by printer Q during the same three days is 10 : 9.
