A bus for Shiridi leaves after every fifty two minutes from a bus stand. An enquiry officer told a passenger that the bus had already left sixteen minutes ago and the next bus will leave at 08:15 p.m. At what time did the enquiry officer give the information to the passenger?
Answer: C
Correct answer: 07:39 p.m
Buses leave every 52 minutes, so the one before the 8:15 bus left at \( 8{:}15 - 52\text{ min} = 7{:}23 \). That bus had gone sixteen minutes earlier, which puts the conversation at \[ 7{:}23 + 16\text{ min} = \mathbf{7{:}39\ p.m.} \]

How many 3’s are there in the following sequence which is neither preceded by nor immediately followed by 9?
9 3 6 6 3 9 5 9 3 7 8 9 1 6 3 9 6 3 9
Answer: D
Correct answer: None of these
Every 3 in the list either has a 9 immediately before it or a 9 immediately after it: the 3s at the second, fifth, ninth, fifteenth and eighteenth places are all disqualified on one count or the other. Not one of them survives both tests, so the answer is none of these - there are no such 3s at all.

A gets more marks than B but less than C. D gets less marks than E but more than A. If C gets less than D then who amongst A, B, C, D, E gets the highest marks?
Answer: C
Correct answer: E
Putting the comparisons together: \( \mathrm{C} > \mathrm{A} > \mathrm{B} \), \( \mathrm{D} > \mathrm{A} \), \( \mathrm{E} > \mathrm{D} \) and \( \mathrm{D} > \mathrm{C} \). So the order is \[ \mathrm{E} > \mathrm{D} > \mathrm{C} > \mathrm{A} > \mathrm{B} \] and E has the highest marks.

In a class of 180, where girls are twice the number of boys, Rupesh[a boy] ranked 34th from the top. If there are 18 girls ahead of Rupesh, how many boys are after him in rank?
Answer: B
Correct answer: 44
Girls are twice the boys, so of the 180 there are 60 boys and 120 girls. Rupesh is 34th, with 33 pupils ahead of him, of whom 18 are girls - leaving 15 boys ahead. Rupesh is therefore the 16th boy, and the boys behind him number \[ 60 - 16 = \mathbf{44} \]
