Answer 1

The bag contains b number of beads. He gave 20 beads to his sister. This means 20 beads was subtracted from b number of the beads.

b = number of beads in the bag

He gives 20 bead to his sister. Therefore,

b - 20

splitting the beads into 4 groups

`\text{ bead on each necklace = }(b-20)/(4)`
