The percentage of respondents aged less than 40 years is at least ___.
Answer & solution
- A
10%
- B
16.67%
- C
20.0%
30%
Males with their ages = 38, 32, 21, 32, 33
Females with their ages = 34, 35, 27, 37
∴ Minimum number of respondents aged less than 40 = 5 males + 4 females = 9
∴ Required percentage = × 100 = 30%
Hence, option (d).
