A) 10 B) 18
C) 12 D) 15
 
Answer & Explanation Answer: A) 10

No. of one rupee stamps = 3
Now, remaining money = Rs. 17
With that he buys only 2 and 5 rupee stamps
Let number of Rs. 5 stamps = K
Let number of Rs. 2 stamps = L
5K + 2L = 17
K = 3, L = 1 (possible)
L = 6, K = 1 (possible)
=> But given that they are different in number so, K is not equal to 3
one rupee stamps = 3
2 two stamps = 6
5 rupee stamps = 1
Total number of stamps = 10.

A) 126 B) 120
C) 146 D) 156
 
Answer & Explanation Answer: A) 126

There are 8 students and the maximum capacity of the cars together is 9.


We may divide the 8 students as follows


Case I: 5 students in the first car and 3 in the second
Case II: 4 students in the first car and 4 in the second


Hence, in Case I: 8 students are divided into groups of 5 and 3 in8C3 ways.


Similarly, in Case II: 8 students are divided into two groups of 4 and 4 in 8C4ways.


Therefore, the total number of ways in which 8 students can travel is:
8C3+8C4=56 + 70= 126
