Yen has some beads in a bag. The number of beads is less than 30. If she gives 5 beads to each pupil, she will have none left. If she gives 8 beads to each pupil, she will need 12 more beads.
- How many pupils does Yen have?
- How many beads are there in the bag?
(a)
Total extra number of beads that Yen will need = 12
Number of extra beads that Yen will give to each pupil
= 8 - 5
= 3
Number of pupils that Yen has
= 12 ÷ 3
= 4
(b)
Number of beads that Yen has
= 5 x 4
= 20
Answer(s): (a) 4; (b) 20
