Read Solution (Total 3)

at start of seminar total participants=3x+x=4x
at tea break 16 left and 6 added i.e=4x-16+6=4x-10
now total participants eqal to 2x+1x=3x
so 4x-10=3x
x=10
initially total paticipants are 4x=4*10=40 hence answer is A(none)

3:1 means 3x and x=4x nox 16 left 4x-16 which is equal to next ratio 2:1 ie 2x and x=3x
therefore4x-16=3x=>x=16 and total befor 4x =>4*16=64
