Increase = 55
% increase
= (55/65) x 100%
= 84.6%

Well it seems that you've got plenty of correct answers. Just to help you. You mentioned that you new that the percentage increase would be 100% if you were to increase it from 65 to 130, so just apply the same rule to 120.
So 65 has been increased by another 65. 65 divided by 65 = 1. Multiply by 100 gives you 100%. In this case, however, 65 has been increased by 55 so just apply the same rule.
Easy huh!

The actual increase you need is 120 - 65 = 55, so the
question is asking you to express 55 as a %age of 65. As a
fractional increase, this is 55/65, and you now have to
express this as a %age, which you do by multiplying 55/65 by
100:
55/65 x 100
=84.62%, correct to 2 d.p. Hope this helps, Twiggy.

= increasing in growth / actual value x 100%
= (120 - 65) / 65 x 100%
= 55 / 65 x 100%
= 84.62% >>>>>>>>>4 significant number

increase = 120 - 65 = 55
% increase = 55/65 = 0.84615 or 84.615%

you work out the increase then divide the increase by the original number, multiply by 100,
120-65=55
(55/65)*100
=84.61538462

growth= (final number-initial number)/initial number * 100
=120-65/65 *100
=55/65 *100
= 84.615 %

Hiya!
Actual increase is 120-65 = 55
Percentages are found by dividing increase by original number & multiplying by 100.
55/65x100 = 84.6153846 etc
Therefore the percentage increase is approx. 84.615%; the exact figure being 84 8/13 %.
I hope this helps - but again feel free to drop me a line if you'd like me to say more

% increase=(increase in number/original number)*100
={(120-65)/65}*100
=(55/65)*100
=(11/13)*100
=1100/13
=84.6153...
or84+(8/13)

To get from 65 to 120......
120 / 65 = 1.846
1.846 * 100% = 184.6 % increase
(From your point of view you are not counting the original number, so it is an 84.6% increase!)
