Que: According to the table given below, a state has a total of 23,000 numbers of companies from seven regions. By what percent of the total number of companies in the region, the number of companies of Region V is more than the number of companies of Region T, approximately?
Region-wise distribution of companies in the state
Region P ------------- 1,100
Region Q ------------- 2,525
Region R ------------- 1,800
Region S ------------- 2,100
Region T ------------- 2,750
Region U ------------- 150
Region V ------------- 3,500
(A) 25.1%
(B) 44%
(C) 19.7%
(D) 5.4%
(E) 27.27%
Solution: Number of companies in region V = 3,500 and the number of companies in region T = 2,750Thus, Percent change: After – Before/ Before * 100(%) [After:3,500 ; Before: 2,750, since ~than Before, so Region T becomes Before]
=> \(\frac{(3,500 – 2,750) }{ 2,750}\) * 100(%)
=> \(\frac{750}{2,750}\) * 100(%) = 27.27%
Therefore, E is the correct answer.
