  hey goyal check out your option b,c,d put the "+"sign in the place of "*".
  i think 5+(5/11)min. past 7 is correct.
  because hour hand will suffer some distance from 7 when minute hand arive on 5.

  solution:
  at 7 o'clock ,the minute hand will be on 12
  means minute hand and hour hand are 25 minute space apart
  so for being in the straight line the minute hand will have to move 30-25=5 minute
  as we know that 55 spaces are gained by 60 minutes
  therefore 5 minutes will be gained in=(60/55)x5
  =5.45 minute
  or 5+5/11 minute past seven
  so both hands will be in straight line but not together at 5+5/11 minute past 7
  hope this will be the right answer
  and gd explanation

  solution for second:
  as the watch is 2 minute slow at monday noon and 4 minute 48 seconds fast at following monday at 2 pm
  means in (24x7+2)=170 hours watch fasts (2+4 min 48 seconds)=360+48=408 seconds
  there fore the equatio will be like this
  408 seconds fast will be in =170 hours
  1 '' '' ..........................=170/408 hours
  120 seconds(to cover 2 minute slow)=170x120/408
  = 50 hours
  so the watch will show right time after 50 hours
  and that time will be 2pm. on wednesday
  I think this solution should also be correct
  so option 'B' will be the right answer
  plz tell me
  am I correct or not?
