(I) Less than type

Age (in year)       Number of patients

Under 10             0

Under 20             60 + 0 = 60

Under 30             60 + 42 = 102

Under 40             102 + 55 = 157

Under 50             157 + 70 = 227

Under 60             227 + 53 = 280

Under 70             280 + 20 =300

(II) More than type

Age (in year)       Number of patients

More than or rises to 10               60 + 42 + 55 + 70 + 53 + 20 = 300

More than or rises to 20               42 + 55 + 70 + 53 + 20 = 240

More than or approaches 30       55 + 70 + 53 + 20 = 198

More than or approaches 40       70 + 53 + 20 = 143

More than or rises to 50               53 + 20 = 73

More than or approaches 60       20

More than or rises to 70               0
