A. 25% B. 55% C. 100% D. 125% E. 155% State A  181,000 State D  79,000 A is what % greater than D approximately? Let's round up D = 80,000 100% increase => D = 160,000 => A,B,C can be safely eliminated. 150% increase => D = 200,000 < Already too big => E can safely be eliminated. D is the answer i.e. approximately 125% increase.

A. 25% B. 55% C. 100% D. 125% E. 155% Approximate. The number of home schooled children in A is 180 and that in D is 80. We need to find by what percentage is A greater than D. A is 100 greater than D. If A were 80 greater than D, it would be 100% greater. If A were 80 + 40 = 120 greater than D, it would be 150% greater. It is right in the middle of the two  i.e. it is 100 greater hence it is 125% greater than D. Answer (D)

asfandabid wrote: Can you please explain again in simpler terms Sure. According to the table, \(A = 181\) \(D =79\) Difference of \(A\) and \(D\) will give how much is \(A\) greater than \(D\). Therefore, \(A  D = 181 79 = 102\) Required percent = (Difference of \(A\) and \(D\) \(/\) \(D) * 100= \frac{102}{79}\) * 100 As the question is asking the approximate value, we can approximate the above fraction Therefore; \(\frac{102}{79}*100 =\) (Approximately) \(= \frac{100}{80} * 100 = 125\) % Answer (D) Hope its clear now.

A. 25% B. 55% C. 100% D. 125% E. 155% We can set up the following expression: (181,000  79,000)/79,000 x 100 Estimating, we have: (180,000  80,000)/80,000 x 100 100,000/80,000 x 100 10/8 x 100 = 5/4 x 100 = 125% Answer: D
