price= "p"
real cost= 12 apples * "price p" = 12p
discounted cost= 12 apples * (p-1) = 12(p-1)
so,
=> real cost - discounted cost = an extra apple at price "p"
=> 12p - 12(p-1) = p
=> 12p - 12p + 12 = p
Therefore, p = 12.
is this okay ? to be honest i couldnt find the equation on the 1st try so i just tried the answer with all the given options... meaning i had input every option once to see if it works... is this what i should do everytime i get confused on making a proper equation in between the first 30 seconds just try out all the options?? please suggest...
Hi Fazze..I didn't understand your approach..
you considered price per apple as p
last equation suggests that p=12
and as per my understanding the original cost(without discount) of the dozen apples must cost
12p= 12 * 12
and also according to the below equation of yours
discounted cost= 12 apples * (p-1) = 12(p-1)
doesn't this imply 12p-12 which implies it was Rs 12 , which was discounted from the dozen apple's price.
am I missing some point any where or is there any flaw in your approach..
Thank you,
Vivek.
