1. For statement 1
Here the total number of occupational injuries = 59.2
No. of age group constitute more than 15 % are-
group 25 -34, which constitute 18.6 which is greater than 15%
group 35 - 44 which constitute 15.7 which is greater than 15%
group 45 -54,which constitute 9.5 which is greater than 15%
Hence option is C i.e 3 groups.
2. Statement 2
Here the no. of injuries till the age group 34 = 28000
out of which 14000 injuries are incurred by men.
Therefore no. of injuries incurred by men over age group 35 = 39400-14000 = 25400
i.e option D
3. Statement 3
Here the total number of workweeks lost due to occupational injuries in the 55-64 age-group in 1998 =\(5200 * \frac{48.5}{40}\) = 6300
