## TCS Digital Analytical and Logical Questions and Answers

We have still made these pages live as we got mail from about 600+ students to not wait for 2 more days to make the TCS Digital Dashboard live.

But, make it live as is and we are working on this Dashboard simultaneously.

So benefit for you is that you can atleast study or see a bit of the pattern and questions and don’t have to wait for 2 more days.

We care for you :). Which is why your love has made PrepInsta India’s Number 1 website for Placements.

Ques. 2

In the following questions, 16 cells are shown. The objective is to get three clusters of four cells each, which each cluster having a common property, and the remaining cells in a fourth cluster of unrelated names.

Once the clustering is done, the cell identifiers (a to p) for the cells in each of the first three clusters need to be given, with one cluster per line with commas (but no spaces) separating the cell identifiers for each cell in the cluster.

For example suppose one cluster is a,c,d,p the second cluster is b,m,e,g the third cluster is o,f,j,n and the (unrelated) cluster is h,i,k,l Then corresponding output could be (the first three clusters can be in any order),

b,e,m,g o,f,n,j a,c,d,p

Ques. 5 The following note gives one part of a position paper on the future of Life Science. Please read the passage, and identify which of the indicated technologies would be useful for these trends strictly based on the passage. Note that more than one technology may be applicable

Life sciences companies are focusing on keeping patients digitally informed with accurate medical information on diseases, related drugs, and devices through microsites, mobile apps, and informative videos. Rather than replacing healthcare providers (HCPs), the digital medium will complement the quality of healthcare available for patients. Platforms or patient healthcare portals such as ChARM PHR help users manage not just their personal health records and medication history but also care plans, immunization records, health and wellness tips, and so on. patientslikeme and other such patient networking portals connect people with similar medical conditions and help them better understand medication regime, side effects, and cost impact, among others.

In such patient networks, some members are key influencers or ‘digital opinion leaders’. Life sciences companies can collaborate with these community leaders to share their opinions and information related to new therapies, trials, and care methods with others. Social networking sites can also provide information on specific campaigns to access drug vouchers, coupons, health-tips, and so on. Companies are leveraging social media channels by creating community pages for disease condition information well within the required compliance and regulation. Unimetric’s report on pharma-social-media-trends states that most of the pharmaceutical companies are active on five out of six social networks with the majority preferring Twitter, LinkedIn, Facebook and YouTube. MerckEngage is one such communication channel available across social media.

Digital technologies are now being leveraged to reduce medication non-adherence too with mobile-based trackers and schedulers, sensor-based devices such as inhalers, smart pillbox, and smart pills. Sensor-enabled medical devices such as oximeter and blood glucose monitor are capturing vital health stats for patients using their smartphones. These are transmitted to physicians and care teams, who provide patient-specific recommendations.

The selected technology ids (a,b and so on) needs to be entered in the blank area separated by commas. For example, if you think only a and h are valid, the answer line should be
