total 100 beads
56 pink
44 blue
24 are removed.

Option 1:
after removal pink=blue
So 56-x=44-y
and x+y=24
56-(24-y)=44-y
32+y=44-y
2y=12=>y=6,x=18
remaining blue=44-6=38 hence sufficient.

Option 2 :
ratio of beads removed 3:1 =pink:blue
24 in total removed.
so number to pink removed should be 18 pink and blue should be 6.
Remaining blue then will be 44-6=38. Sufficient .

Answer is option D


Bunuel
A jar contains 100 glass beads, of which 56 are pink and 44 are blue. If 24 beads are removed from the jar, how many of the beads remaining are blue?

(1) After the 24 beads are removed, the number of pink beads remaining in the bag equals the number of blue beads remaining in the bag.
(2) Of the beads removed, the ratio of the number of pink beads to the number of blue beads is 3 to 1.

Pink bead removed= P and Blue beads removed= B
P+B=24
Remaining pink beads= 56-P
Remaining Blue beads = 44-B

(1) After the 24 beads are removed, the number of pink beads remaining in the bag equals the number of blue beads remaining in the bag.
56-P=44-B
P-B=56-44=12 and P+B=24
Solving, we get P=18 and B=6
Sufficient

(2) Of the beads removed, the ratio of the number of pink beads to the number of blue beads is 3 to 1.
P/B=3x/1x
3x+1x=24 ; 4x=24 ; x=6
B=6 and P=18
Remaining Blue= 44-6=38
Sufficient

D
