Answer 4

The increase in the quantity = (75,000 - 34,161.78)
The fractional increase in the quantity = increase in quantity / original quantity
= (75,000 - 34,161.78) / 34,161.78
= 1.195436

The percentage increase means the increase per 100 of the original quantity, so one has to multiply by 100.

Percentage increase in quantity = 1.195436 x 100 = 119.5436%

A common error

A 200% increase is an increase of 200 per 100 (i.e. 200 for every 100), so the quantity has grown from 100 to 300. The new quantity is three times as great (3x). A lot of people wrongly interpret a 200% increase as meaning that a quantity has doubled in size!

Similarly a 300% increase means a quantity has grown to 4 times its original size.

This is why percentages are a cause of so much confusion and errors (not least amongst newspaper reports). It would be far better if they were avoided wherever possible.

Answer 5

Percentage increase/decrease
In general, if a quantity changes from one value to another then
Percentage Change = [100 × (difference in the values)/old value]


In your example, figure of 34,161.78, which increases to 75,000.
The percentage increase is [100 × (75000 - 34161.78) / 75000] = 54.45%

Answer 6

If you start with two baseballs and wind up with three, the increase is one baseball. The 'percentage increase' is one divided by two times 100 = 1/2 x100 = 50%. (A 100% increase would double the baseballs to four.) Three baseballs are 150% of two baseballs. But you asked for percentage 'increase.'

Answer 8

75000 - 34161.78
=> increase = 40838.22

increase/original * 100/1 %
= 40838.22/34161.78 * 100/1 %
= 119.54%

Answer 9

Increased price (a)
original price (b)
a - b = x
x/a x 100 = % increase

Answer 10

Increase = 75,000 - 34,161.78
Increase = 40,838.22
% increase:-
= (40,838.22 / 34,161.78) x 100%
= 120% (to nearest whole number)
