Let total Number of pearls be x


number of pearls lost = x/3


number of pearls missing = x/4


remaining = 20


==>  x = x/3 + x/4 + 20


==> x = (4x+3x)/12 + 20


==> x = (7x + 240) / 12


==> 12x = 7x + 240


==> 5x = 240


==> x = 240/5 = 48 !!


 


therefore total number of pearls originally is 48 !
