Limin has 100 more beads than Pauline at first.
After Pauline gave 50 beads away,
100 + 50 = 150
This means that Limin now has 150 more beads than Pauline.
Limin also has twice as many beads as Pauline.
Let Number of bead Pauline have be 1 unit.
Number of bead Limin have will be 2 units.
1 unit + 150 = 2 units.
1 unit = 150
Pauline now has 150 beads
After Pauline gave 50 beads away,
100 + 50 = 150
This means that Limin now has 150 more beads than Pauline.
Limin also has twice as many beads as Pauline.
Let Number of bead Pauline have be 1 unit.
Number of bead Limin have will be 2 units.
1 unit + 150 = 2 units.
1 unit = 150
Pauline now has 150 beads
