A. 93%
B. 97%
C. 100%
D. 107%
E. 120%


Say Arthur's fortune was $100. Then:

A = 20*1.5*1.1 = 33
B = 20*1.5*1.1 = 33
C = 20*1.5*0.4 = 12
D = 20*0.6*1.25 = 15
E = 0

Total 33 + 33 + 12 + 15 = 93.

Answer: A.

B = 20*1.5*1.1 = 33
C = 20*1.5*0.4 = 12
D = 20*0.6*1.25 = 15
E = 0

Total 33 + 33 + 12 + 15 = 93.

Answer: A.


I think Bunuel's approach is fast enough. Anyways, one could use 100 as the total and then play with the numbers, its not that hard.

Hope it helps
Cheers!

B. 97%
C. 100%
D. 107%
E. 120%


Simple -x as Artuhur's investment divided by 5 - let x be 2000

2000/5= 400

400(1.5) = 600 (3)

400(.60) = 240 (2)

Second Year


600(1.1) = 660 (2)
600(.40) = 240
240 (1.25) = 300

660(2) + 240 + 300 = 1860/2000

186/200 =93/100

Thus
"A"

Percent fortune received by each of A, B, C, D, E = 20%.

Value of the fortune after the first year:
A - 30
B - 30
C - 30
D - 12
E - 12

Value of the fortune after the second year:
A - 33
B - 33
C - 12
D - 15
E - 0

If we assume the initial fortune to be $100, what's left would be $33 + $33 + $12 + $15 = $93 = 93%. Ans - A.

I took around 3 minutes to solve this question. Though this question is quite easy, but is there any way that I can save some time
