Jade has some beads in a bag. The number of beads is less than 20. If she gives 3 beads to each pupil, she will have none left. If she gives 8 beads to each pupil, she will need 20 more beads.
- How many pupils does Jade have?
- How many beads are there in the bag?
(a)
Total extra number of beads that Jade will need = 20
Number of extra beads that Jade will give to each pupil

= 5
Number of pupils that Jade has
= 20 ÷ 5
= 4
(b)
Number of beads that Jade has
= 3 x 4
= 12
Answer(s): (a) 4; (b) 12
