60 po yan.. I think.

5% + 1/4 + 1/2 + 12 = n

where n = total number of marbles

simplifying:

4/5 + 12 = n
4/5 - n = -12
- 1/5 = -12

n = 60

60 is the answer since may clue ka ng 12 white marbles which is 20% of the total number of marbles in the jar then ginawa ko na lang is (12*2)+(12*2) = 30 which is now the 50% of the total number of marbles then multiply mo lang ulit by 2 then 60 ang answer

p.s. not really sure about this xd bob0 ako sa math :3

1/4 plus 1/2 =3/4 equivalent to 75%
Black marble is 5% total is 80% so white marble is 20%..just divide 12 by 20%
