Answer: 186
Step-by-step explanation:
Jazz Rock or Pop
7-12: 200 - 142 = 58 142
13-18: 72 - 58 = 14 200 - 14 = 186
It is given that 142 out of 200 students in age group 7-12 like Rock or Pop.
Therefore, 200-142 = 58 in that age group like Jazz.
Total Jazz in both age groups is 72, so 72 - 58 (7-12: Jazz) = 14 students in age group 13-18 like Jazz.
There are 400 students total and 200 are in age group 7-12, which leaves 400-200 students in age group 13-18. 200 - 14 (13-18: Jazz) = 186 students in age group 13-18 like Rock or Pop.
