Question 32524
Let the number of people last year = x 

and we are given that this year there is 12% increase ...so 

number of people walked this year = x + 12%
or on solving we get = (112/100)x

now we are also given that 1344  people walked this year ....so we get 

(112/100)x = 1344

multiply both sides by 100    and we get

112 = 134400

divide both sides by 112/ ,,,and we  get     ...

x = 1200

so number of people walked last year are 1200...

Hope this will help you
