% Increase = \(\frac{Difference}{Smaller. Number}\) x 100
% Decrease = \(\frac{Difference}{Larger. Number}\) x 100
Opening Value of stock X = $40 and closing value = $41
% Increase = \(\frac{41 - 40}{40}\) x 100 = \(\frac{1 - 40}{40}\) x 100 = 2.5%
Opening Value of stock Y = $25 and closing value = \(\frac{3.5}{25}\) x 100 = $28.5
% Increase = \(\frac{28.5 - 25}{25}\) x 100 = 14%
The difference in percentage points points for the 2 stocks = 14 - 2.5 = 11.5%
Option D
Please Note: To calculate 3.5/25it is better to convert 3.5 to a whole number = 35/250 = 7/50 = 0.14
But in the sum above, this would not be required as you have 100 in the numerator which is divisible by 25, and so (3.5 / 25) * 100becomes 3.5 * 4 = 14

Percentage increase in Share X = (41-40)*100/40 = 2.5%
Percentage increase in Share Y = (28.5-25)*100/25 = 14%
14-2.5 = 11.5%
D is the answer.
Hope it helps.
