A stamp collector has the habit to arrange or rearrange the stamps accordingly. while doing this he some times keeps the stamps in pairs, or in group of 3 or in 4 or in or in 6 and realises that in any case he is left with 1 stamp and when he arranges them in groups of 7 no stamps remain. what is the number of stamps he has?

• 49.we have to consider the l.c.m of (2,3,4,6).
  so the answer should be in terms of [(multiples of 12)+1].since it should not be divisible by 2,3,4,6.
  so the number is 49,which leaves remainder 1 in each case when divided by(2,3,4,6) and no remainder when divided by 7.
