#LRDIoftheDay #48 Easy one for today

The following pie charts give the number of employees at UltraTech at the end of the year for the period 2012 to 2015. The charts also capture the education qualification of the employees. UltraTech does not employ people who are not at least matriculates and once a person gets recruited, he cannot pursue further education. It is also known that no employee of the company left the job during the given period.

NOTE: It is necessary for a doctorate to be a post graduate, for a post graduate to be a graduate and for a graduate to be a matriculate. This means that the number of matriculates also include those who went on to do their graduation, post graduation, doctorates. Similar is the case for the numbers of graduates and post graduates. If the answer to any question cannot be uniquely determined, type in 0 as your answer.

1. How many graduates joined UltraTech in the year 2014?

2. How many post graduates who were not doctorates joined UltraTech in 2014 and 2015 put together?

3. How many employees joined UltraTech in the year 2013?

4. What was the absolute difference between the number of doctorates who joined Ultra Tech in the year 2013 and 2015?
