94
так как это двузначное число и оно должно быть больше суммы своих цифр на 81 это уже будет число больше 81
цифра десятков на 5 больше цифры единиц и при этом больше 81 подходит только 83 и 94, методом исключения остается только 94

Пожалуйста, помогите корректно перевести данный текст на русский язык, что бы было без странных словосочетаний, которые образуются после прогонки через переводчик...

I’ve been doing some research into what people in Britain think of doctors, the ones who work in general practice – the first call for me medical care – and comparing this with the situation in a couple of the countries. I want to talk about the rationale behind what I decided to do.

Now I had to set up my programme of research in there different countries so I approached postgraduates in my field in overseas departments(Q31), contacting them by email, to organize things for men at their end. I thought I would have trouble recruiting help but in fact everyone was very willing and sometimes their tutors got involve too.

I had to give my helpers clear instructions about what kinds of sample population I wanted them to use. I decided that people hat people under 18 should be excluded because most of them are students or looking for their first job, and also I decided at this stage just to focus on men who were in employment(Q32), and set up something for people who didn’t have jobs and for employed women later on as separate investigation.

I specifically wanted to do a questionnaire, and interviews with a focus group. With the questionnaire, rather than limiting it to one specific point, I wanted to include as much variety as possible(Q33). I know questionnaire area very controlled way to do things but I thought I could do taped interviews later on to counteract the effects of this. And the focus group may also prove useful in future, by targeting subjects I can easily return to, as the participants tend to be more involved.

So I’m collating the results now. A the moment it looks as if, in the UK, despite the fact that newspaper continually report that people are unhappy with medical care, in fact it is mainly the third level of care, which takes place in hospitals, that they are worried about(Q34). Government reforms have been proposed at all levels and although their success is not guaranteed, long-term hospital care is in fact probably less of an issue than the media would have us believe. However, I’ve still got quite a bit lot of data to look at.

Certainly I will need to do more far-reaching research than I had anticipated in order to establish if people want extra medical staff invested in the community, or if they want care to revert to fewer, but larger, key medical units(Q35). The solution may well be something that can be easily implemented by those responsible in local government, with central government support of course.

This first stage has proved very valuable though. I was surprised by how willing most of the subjects were to get involved in the project – I had expected some unwillingness to answer questions honestly. But I was taken aback and rather concerned that something I thought I’d set up very well didn’t necessarily seem that way to everyone in my own department(Q36).

I thought you might also be interested in some of the problems I encountered in collecting my data. There were odd cases that threw me –one of the subjects who I had approached while he was out shopping in town, decided to pull out when it came to the second round (Q37). It was a shame as it was someone who I would to have interviewed more closely.

And one of the first-year students I interviewed wanted reassurance that no names would be traceable from the answers(Q38). I was so surprised, because they think nothing of telling you about surprised, because they think nothing of telling you about themselves and their opinions in seminar groups!

Then, one of the people that I work with got a bit funny. The questions were quite personal and one minute he said he’d do it, then the next day he wouldn’t, and in the end he did do it(Q39). It’s hard not to get angry in that situation but I tried to keep focused on the overall picture in order to stay calm.

The most bizarre case was a telephone interview I did with a teacher at a university in France. He answered all my questions in great detail – but then when I asked how much access he had to dangerous substances he wouldn’t tell me exactly what his work involved (Q40). It’s a real eye- opener…
