⟩ A stamp collector arranges his stamps during his free time. When he arranges his stamps in pairs, there is one stamp left. It is the same when he arranges the stamps in groups of 3, 4, 5 and 6. Now, how many stamps will he be left with when he arranges them in groups of 8?
Total stamps are the l.c.m of 3,4,5,6 i.e 60 and 1 is the remainder in all the cases.. so the toal stamp is 60+1=61
now deviding 61 with 8 leaves the remainder 5
so if he want to make it a group of 8 he ll be having 5 stamps left
