There are 100 students who appeared in an entrance examination that had three sections: Quantitative Ability (QA), Data Interpretation (DI) and English Usage (EU). The number of students who cleared the cut-off marks in QA, DI and EU is 43, 65 and 37 respectively. Every student cleared the cut-off marks in at least one section.
If the number of students who cleared the cut-off marks only in DI is maximum possible, then find the number of students who cleared the cut-off marks in all the three sections.?

Suppose the investment of Rs. 2 lakhs in the above project can be made in two equal installments of Rs. 1 lakh in the beginning of the project and the other Rs. 1 lakh at the beginning of the second year. From the beginning of the third year, the project will generate revenues of Rs. 1.5 lakhs every year. Using the same cost of capital of 10%, what should be the minimum life of the project inclusive of the project implementation phase? (use the 'beginning of the year' convention)
