| Height (in cm) | No. of students |
| up to 150 | 12 |
| up to 155 | 16 |
| up to 160 | 18 |
| up to 165 | 33 |
| up to 170 | 48 |
What is the percentage of students whose height is more than 160 cm ?
Answer & explanation
Correct answer: option 4
Total number of students = 48
Number of students whose height is more than 160 cm = 48 - 18 = 30
Required percentage = \(\frac{ 30 }{48}\) × 100
= 62.5%
