The [mean] average of 5 numbers is 25, so their total is 5 x 25 = 125 The [mean] average of 4 numbers is 25, so their total is 4 x 25 = 100 → the excluded number is 125 - 100 = 25. Alternatively, as the average doesn't change, the excluded number must be the average, ie 25.
% rate:= 125/500 * 100%= 0.25 * 100%= 25%
100 + 25 = 125
125 is 25% of 500
the next number in the sequence 1 5 25 125 is 625
25% of 125= 25% * 125= 0.25 * 125= 31.25
25 times 5 is 125. 25 + 25 (2x25) = 50 50 + 50 (4x25) = 100 100 + 25 (5x25) = 125
4,5,6,10,100=125 and their mean is 125/5=25% of the larest number,100
100 + 25 = 125
If you begin with 100 and increase it by 25%, predictably, you end up with 125. But when you decrease it by 20%, we're talking about 20% of the latest result, not of the original number. 20% of 125 is (125)*(0.2) = 25. So 125 - 25 brings you back to 100.You cannot simplify or total the change in percent before calculating, because we're not always talking about the percent of the same number.
1.25 / 25 = 0.05Converting decimal to a percentage: 0.05 * 100 = 5%
percentage = 500%% rate:= 125/25 * 100%= 5 * 100%= 500%
500 = 100% ? = 25 % 100/25 = 4 500/25 = 125 25% of 500 is 125.
