उत्तर
Also, we observe that all 300 patients which take medical treatment more than or equal to 10. Since, thete are 60 patients which take medical treatment in the interval 10 – 20, this means that there are 300 – 60 = 240 patients which take medical treatment more than or equal to 20. Continuing in the same manner.
| More than type | |
| Age (in year) | Number of patients |
| More than or equals 10 | 60 + 42 + 55 + 70 + 53 + 20 = 300 |
| More than or equals 20 | 42 + 55 + 70 + 53 + 20 = 240 |
| More than or equals 30 | 55 + 70 + 53 + 20 = 198 |
| More than or equals 40 | 70 + 53 + 20 = 143 |
| More than or equals 50 | 53 + 20 = 73 |
| More than or equals 60 | 60 |
| More than or equals 70 | 0 |
