Respuesta :
If you add 164 and 208 you get 372. After that you would subtract the original number from 372 ( 372-248) giving you the answer of 124. This means that 124 people do both exercises.
Answer:
124 members
Step-by-step explanation:
Suppose L represents the number of members of lift weight and C represents the number of members who perform cardiovascular exercises,
So, according to the question,
n(L) = 164,
n(C) = 208
n(L∪C) = 248,
∵ n(L∪C) = n(L) + n(C) - n(L∩C)
⇒ 248 = 164 + 208 - n(L∩C)
⇒ 248 + n(L∩C) = 372
⇒ n(L∩C) = 372 - 248 = 124
Hence, 124 members do both lift weights and cardiovascular exercises.
