Kylie 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 6 beads to each pupil, she will need 18 more beads.
- How many pupils does Kylie have?
- How many beads are there in the bag?
(a)
Total extra number of beads that Kylie will need = 18
Number of extra beads that Kylie will give to each pupil
= 6 - 3
= 3
Number of pupils that Kylie has
= 18 ÷ 3
= 6
(b)
Number of beads that Kylie has
= 3 x 6
= 18
Answer(s): (a) 6; (b) 18
