     Instructions for questions 126 to 129. Read the following information and find the answers to the questions: The new remote control that came with the BPL television set has some unusual features. If the T+2 button is pressed, it moves two channels forward from the current channel (i.e., from channel 1 to channel 3). If the PP button is pressed, it returns to the previous channel from the current channel. If the PR button is pressed, it goes to the prime number channel immediately preceding the current channel. Finally, the MAG button, which has no priority flaw, immediately takes you to your most favorite channel. Amit has set Star Plus (Channel 17) as his magic (favorite) channel. (Use the information available in the questions for answers as well) While Star Plus is playing, what is the channel number he arrives at if he presses T+2, PR, PR, PP in sequence to reach this channel?

     • b23సరైన సమాధానం
     • c25
     • d29
     ›వివరణ

     Option B is correct because pressing T+2 moves to channel 25, the first PR moves to 23, the second PR moves to 19, and the PP button recalls the immediately preceding channel, returning to channel 23. Initial channel = 23 Press T+2: advances to channel 25 (previous channel was 23) Press PR: goes to prime preceding 25, which is 23 (previous channel was 25) Press PR: goes to prime preceding 23, which is 19 (previous channel was 23) Press PP: recalls the previous channel, returning to 23 Option A: corresponds to the channel reached after the second PR press, failing to account for the final PP press. Option C: is the channel reached after the first T+2 step, ignoring the subsequent button presses. Option D: incorrectly assumes forward movement rather than the preceding prime channels and toggle recall.

Pressing the PP button takes you back to the channel you were watching before the current one. Pressing the PR button takes you to the next prime-numbered channel ahead of the current one. Last but not least, the MAG button takes you straight to your favourite channel. Amit has made Star Plus (channel 17) his magic (favourite) channel. (Use the information given in the questions as well.) If the currently running channel is Star Plus, which buttons should he press consecutively to watch channel number 25?

     • aT+2, PR, T+2సరైన సమాధానం
     • bPR, PP
     • cT+2, T+2, PR
     • dNone of the above
     ›వివరణ

     Option A is correct because starting from Star Plus at channel 23, pressing T+2 moves two channels forward to 25, pressing PR moves to the immediately preceding prime channel 23, and pressing T+2 again reaches channel 25. Current channel Star Plus = 23 First press T+2: 23 + 2 = 25 Second press PR: preceding prime before 25 = 23 Third press T+2: 23 + 2 = 25 Option B: PR moves backward to a preceding prime and PP recalls the prior channel, neither of which advances the channel forward to 25. Option C: pressing T+2 twice reaches 27, and then PR moves to prime 23 rather than 25. Option D: sequence A successfully achieves channel 25, making this choice incorrect.

Senior cadre available: X, Y, Z; rejecting Y leaves X and Z as the two required senior executives Selecting Z eliminates C because Z and C are not friends Selecting B eliminates A because A and B are not friends Remaining junior engineer to pair with B is D, completing the team as X, Z, D, and B Option A: includes Y, who is explicitly rejected, and pairs A with B against the friendship rule. Option C: pairs Z with C, violating the condition that there is no friendship between Z and C.

     Directions for questions 86 to 90. A company wants to select a team of four mechanical engineers to transfer to a new industrial centre it is about to set up in North India. The company is run by experienced managers and is careful about human resources and industrial relations. There are 7 engineers of equal ability: X, Y and Z (senior executive cadre) and A, B, C and D (junior cadre). The company needs two senior executives in every team. Since a team must also have the right team spirit to resolve industrial-relations problems, all the engineers in a team must be friends. The relations among the 7 engineers are as follows: I. Y and A are not friends. II. Z and C are not friends. III. A and B are not friends. If A is in the team, who will be the other engineers in that team?
