Once I had been to the post office to buy five-rupee, two-rupee and one-rupee stamps. I paid the clerk Rs. 20, and since he had no change, he gave me three more one-rupee stamps. If the number of stamps of each type that I had ordered initially was more than one, what was the total number of stamps that I bought ? Choose the correct option:	A) 10	B) 9	C) 12	D) 8	E) 4
Explanation :   At least two stamps of each type were ordered initially.   So, Rs.2 ( 5 + 2 + 1 ) = Rs.16 have been spent.   That leaves ( 20 – 16 ) = Rs.4.   In this Rs.4, three more stamps of one rupee were given, thus accounting for Rs.19 in all.   Since, one more rupee remains, it means that one more stamps of Rs.1 were bought initially.   So the total number of stamps is 2(of Rs.5) + 2(of Rs.2) + 6(of Rs.1). i.e 10.   10nswer : 10
