Another vote for 12%

Basically it boils down to 1.5 is what % of 12.5

Repair price = 12.5
New price 1.5

% increase = New-Old/Old * 100 = 14-12.5/12.5*100
=12%

Same as Cramya...It shuld be 12%...

As ramya said ..its boils to 1.5 is what % of 12.5

one observation and learning from studying for CAT ( Indian entrance test) is percentages are very very easy 2 calculate and we have to just apply the basics..

Always think in terms of 1% . 10% and multiple .. it makes life very easy

1% of 12.5 = .125
10% = 1.25

thus 1.5 would be
1.25+ .125 + .125
10% +1% +1%
12%..

i kind off benefit a lot from using such strategy .. so thought it would be useful for all...

hope this helps...

When you read a question such as this, start taking notes as you move forward.

12.5 one year
28 two years so it is 14 one year

oh the question is what percent greater than the cost of repairing the used shoes?

14-12.5=1.5

is what percent of 12.5

most of the time these numbers are given with a purpose like

12.5 x 8 = 100 ( If you remember this, you will save some time)

so 1.5/12.5 = ?

simply multiply 1.5 with 8 and find 12.

Most of the GMAT takers will solve problem such as this, but whoever solves fast and RIGHT, will have a better hand when things get tougher to the end!
