a string of pearls such that 1/3 is lost and of that 1/4th is missing, remaining is 20 then actual number of pearls?
ans. 40

• at first 1/3 is lost so remaining is 1-1/3==2/3
  After that 1/4 is missing of 2/3 ==(2/3)*1/4 ===1/6
  remaining === 3 / 6
  so 3x/6 == 20
  x===40(ans)

• 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 !

• Let number of pearls be x
  
  as 1/3 are lost ----> x-x/3=2x/3 are remaining.
  
  as 1/4 of remaining are missing ----> (2x/3)*(1/4)=x/6.
  
  Total (NO PEARLS COUNT)= x/6
  
  Remaining (PRESENT PEARLS COUNT)=(2x/3)-(x/6)=x/2.
  
  from Given x/2=20 ----- > x=40.

• {x-1/3}/3/4=20
  coz 1/4th of it is lost so 3/4 is left

• (1/3 X)/4 = X-20

• {x-1/3x]/3/4=40

• Ans is 48 X/3+X/4+20=X so X=48

• Let the no pearl =x
  and the lost pearl is =((1/3)*x)
  so the remaining pearl is x-((1/3)*x)=2x/3
  of the remaining pearl 1/4 is missing so (2x/3)-((1/4)*(2x/3)=3x/6
  now 3x/6=20
  so x=40 ans
