1.Due to overrun in design, the stage took 3 months, i.e., months 3, 4 and 5. the number of people working on design in the fifth month was 5. Calculate the percentage change in cost incurred in the fifth month. (Due to improvement in Coding technique, this stage was completed in month 6-8 only.)

Solution: % change in the cost incurred in the fifth month,
= [[(100000 – 40000) /40000 } *100] = 150%

2.

7.What is the central angle of the sector corresponding to the expenditure incurred on Royalty?

A. 15
B. 24
