Youngest group (aged 13-18): Number of hours watching entertainment ≈ 32 - 8 ≈ 24
Other two groups: Number of hours watching entertainment ≈ (15 - 10) + (15 - 5) ≈ 5 + 10 ≈ 15

So, ratio ≈ 24/15 ≈ 25/15 ≈ 5/3 = 5:3

Answer: D

average number of hours per week that the youngest age group (13-18 yrs) spent watching entertainment= 33-8= 25

average number of hours that the other two groups combined spent watching entertainment= 5+10= 15

So, ratio= 25/15 = 5:3.

So, I think, D. :)

Average number of hours spent on entertainment by the youngest group = 32 - 8 = 24
Average number of hours spent on entertainment by the other two groups = (15 - 10) + (15 - 5) = 15
Ratio = 24 : 15 = 8 : 5 = 1.6
The best option is option D
