Direction for questions 1 to 4: In each question there are two statements: A and B. Choose 1 if the question can be answered by one of the statements alone but not by the other. Choose 2 if the question can be answered by using either statement alone. Choose 3 if the question can be answered by using both the statements together but cannot be answered using either statement alone. Choose 4 if the question cannot be answered even by using both the statements A and B.

3. 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. Solution: From Statement A, Also the last label obtained by her is S. But this is not sufficient to get the number of P's. : Statement A alone is not sufficient. From Statement B, The number of O's and A's is 18. But this is also not individually sufficient to arrive at the required answer.. Statement B alone is not sufficient. After combining both the statements A and B, we can conclude that 18 out of 21 coupons are O's and A's and that the 21st is an S. This means that the remaining two are P's. Hence, option 3.
