The ratio of the total number of people surveyed who take coffee more than 3 times a day to the total number of people who do not take coffee at all is-

Answer: Option B

Number of people who take coffee more than 3 times a day
= 410 + 310 + 700 + 1450
= 2870
Total number of people who do not take coffee at all
= 950 + 430 + 620 + 50
= 2050
∴ Required ratio
= 2870 : 2050
= 1.4 : 1
