Soap

by harsh.champ » Tue Feb 09, 2010 5:29 am
Each packet of SOAP costs Rs 10. Inside each packet is a gift coupon labelled with one of the
letters S, O, A, and P. If a customer submits four such coupons that make up the word SOAP, the
customer gets a free SOAP packet. Ms. X kept buying packet after packet of SOAP till she could get one set of coupons that formed the word SOAP. How many coupons with label P did she get in the above process?


A. The last label obtained by her was S and the total amount spent was Rs 210.
B. The total number of vowels obtained was 18.
It takes time and effort to explain, so if my comment helped you please press Thanks button :)

so she got o a p earlier and lastly she got s

A. total spent = 210 --> total 21 soaps... not sufficient
B. 18 vowels means 18 O and A Not clear about s and P...not sufficient

combined
18 Oand A, 2 P and last S

sufficient
ans C

I think there are 2 possibilites combining both, 18 are vowels(O A). Total are 21, last was S. So remaining 2 can be either P or S. Nowhere in the statement 1 days that this was the "First" S.
Correct me if I am wrong folks..!!

If it is not the first S, she would have completed making soap earlier (using letters of course). She waits for the S, meaning she didnt have S earlier
