(3) It does not exceed
(4) Cannot be determined

3. What is the remainder when 7700 is divided by 100?
4. Balram, the local shoe shop owner, sells four types of footwear – Slippers (S), Canvas Shoes (C), Leather Shoes (L) and Joggers (J). The following information is known regarding the cost prices and selling prices of these four types of footwear:
(i) L sells for Rs.500 less than J, which costs Rs.300 more than S, which, in turn, sells for Rs.200 more than L.
(ii) L costs Rs.300 less than C, which sells for Rs.100 more than S,
which, in turn, costs Rs.100 less than C.
If it is known that Balram never sells any item at a loss, then which of the following is true regarding the profit percentages earned by Balram on the items L, S, C and J represented by l, s, c and j respectively?
(1) l ≥ c ≥ s ≥ j (2) c ≥ s ≥ l ≥ j (3) l ≥ s ≥ c ≥ j (4) s ≥ l ≥ j ≥ c

(1) 7 (2) 6 (3) 9 (4) 8
6. Some friends planned to contribute equally to jointly buy a CD player. However, two of them decided to withdraw at the last minute. As a result, each of the others had to shell out one rupee more than what they had planned for. If the price (in Rs.) of the CD player is an integer between 1000 and 1100, find the number of friends who actually contributed?
(1) 21 (2) 23 (3) 44 (4) 46
DIRECTIONS for questions 7 and 8: Answer the questions on the basis of the information given below.
A robot is designed to move in a peculiar way and it can be set in motion by a microprocessor program. The program can be initiated by assigning a positive rational value to its variable n. The program directs the robot to move in the following way. As soon as the program is started, the robot starts from the point O, moves 2n metres northward and changes its direction by n° to the right. It then moves 2n metres forward and again changes its direction by n° to the right and continues in this manner till it reaches the starting point O, or till it covers a total distance of 1000 m, whichever happens first, and then it stops.
7. I assigned a value for n and started the program. If the robot finally came back to O and stopped, what is the total distance that it has covered?
(1) 180 m (2) 360 m (3) 720 m (4) Cannot be determined
8. For how many values of n in the intervals [1, 60] does the robot cover less than 1000 m, before it stops?
(1) 19 (2) 60 (3) 355 (4) Infinite
DIRECTIONS for questions 9 to 17: Answer the questions independently of each other.
9. If N = 888Dup to 100 digits, what is the remainder when N is divided by 625?
(1) 128 (2) 138 (3) 338 (4) 388
10. If [log101] + [log102] + [log103] + [log104] + …… + [log10n] = n, where [x] denotes the greatest integer less than or equal to x, then

11. A regular polygon has an even number of sides. If the product of the length of its side and the distance between two opposite sides is of its area, find the number of sides it has.
(1) 6 (2) 8 (3) 20 (4) 16
12. There are three cities A, B and C, not on the same straight road. Two buses P and Q start simultaneously from A and B respectively towards C. By the time Q reaches C, P is exactly halfway to C. Immediately after Q reaches C, it starts travelling towards A and it crosses P at a point 165 km from A. The ratio of the speeds of P and Q is 3 : 5. Assume that the roads joining A to C, B to C and B to A are all straight roads. If B is twice as far as from A as it is from C and P would take to cover the distance from A to B, how much time would Q take to cover the distance from C to A?
(1) 2 2/5 hours (2) 3 hours (3) 3 3/5 hours (4) 4 hours
13. Two positive real numbers, a and b, are expressed as the sum of m positive real numbers and n positive real numbers respectively as follows:
a = s1 + s2 + D..+ s m and
b = t1 + t2 + D..+ tn
