Answer 1

(Q). If the no of employees in region 4 remained the same next year, but the number of people attending training increased to 15000, then the % of employees attending the training will be - 45.20%. Answer will be (C).

Because the number of total employees in region 4 is 37% of 89,700 = 33,189. Among this 33,189, 15,000 employees attended training and this % is (15000/33189)*100 = 45.1956% and it is close to 45.20%. Therefore the answer is (C) i.e 45.20%.

(Q) Which company had the smallest proportionate increase in total spending from year 4 to year 5 ?

Company A's total spending increased from 19903 to 22556 in year 4 to 5. Therefore total increased 22556 - 19903 = 2653. Proportion increased is 2653/19903 = 0.1332

Company B's spending increased equal to 32,338 - 27,254 = 5134. So proportionate increase will be 5134/27254 = 0.1883

Company C's spending increased equal to 28,287 - 27842 = 445. So propionate increased will be 445/27842 = 0.0159

Company D's spending increased equal to 23107 - 23559 = -452. In case of company D , it is not increasing in year 5, rather it is decreasing from year 4 to 5.

So smallest proportionate increase is happening in case of company C. As 0.0159< 0.1332<0.1883. Therefore the answer is C. Company C.

(Q). If between year 5 and year 6, company A's proportion of expenditure ....

From year 5 to year 6 the expenditure on upstream exploration increased by 5%. In 2005 it was $17,398 million. So in year 6 it will be $17398*105/100 = $17,398*1.05 = $18267.9 million = $18268 million approx. Therefore the answer is (A). $18268 million.
