Sarah 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 15 more beads.
- How many pupils does Sarah have?
- How many beads are there in the bag?
(a)
Total extra number of beads that Sarah will need = 15
Number of extra beads that Sarah will give to each pupil
= 8 - 5
= 3
Number of pupils that Sarah has
= 15 ÷ 3
= 5
(b)
Number of beads that Sarah has
= 5 x 5
= 25
Answer(s): (a) 5; (b) 25
