By what percentage did the value of the share increase in the five days?

(A) 3.2%
(B) 4%
(C) 5.6%
(D) 7%
(E) 10%

Share price = 30
Final price = \(30 + 1.2 + 3.1 - 4 +2 - 0.2\)
= 32.1
%increase = \((2.1/30)*100\)
= 7%

option D is correct

total price change ; 30+1.2+3.1-4+2-0.2 = 32.1
so % change = 32.1-30/30 = 7%
IMO D

(E) 10%


The value of the stock after 5 days is:

30 + 1.2 + 3.1 - 4 + 2 - 0.2

30 + 6.3 - 4.2 = 36.3 - 4.2 = 32.1

We use the percent change formula: Percent Change = (New - Old)/Old x 100. Thus, the stock increased by:

(32.1 - 30)/30 = 2.1/30 = 21/300 x 100 = 21/3 = 7 percent

Answer: D
