Can please someone check my answer:
a)385 data loss incidents took place
b)110 million people were affected by personal data loss incidents
c)3% of all data loss incidents were caused by hard copy theft/loss
d)20% of all data loss incidents were caused by portable media theft/loss
e)15% of data loss incidents were linked to financial services organisations.
f)4.13 million people suffered data loss incidents involving Government ID numbers.
Using the above data calculate:
i)The total number of data loss incidents that were linked to financial
services organisations, to the nearest whole number.
ii)The ratio of the number of people affected by data loss incidents caused by portable media theft/loss to the number of people affected by data loss incidents caused by hard copy theft/loss.
(iii) The percentage of all people affected by a personal data loss incident that involved Government ID numbe
A. 15% of 385 = 57.75 ~ 58
B. 3% of 385 = 11.55 ~ 12
C. 154:22
D. I'm not sure how to calculate?

I don't know why you have four answers, A,B,C, and D? Are you not answering i,ii, and iii ?
i) .15 * 385 = 57.75 = 58
ii) Ratio portable media theft : hard copy theft
20% : 3% = .20/.03 = 6.67
iii) 4.13 mil govern ID no.
Total people 110 mil (from b.)
4.13/110 = 3.75% 
The second 2 answers are wrong.
(ii) percentage is not asked, the ratio is 7:1, 20% of 385=77 and 3% of 385=11.55 giving 77:11.55
(iii) 110x4.13/100 will give your answer 
ii) Also it is asking for the ratio of people and not the data loss incidents so I think 385 is replaces with 110.
