Eva has some beads in a bag. The number of beads is less than 30. If she gives 4 beads to each pupil, she will have none left. If she gives 7 beads to each pupil, she will need 18 more beads.
- How many pupils does Eva have?
- How many beads are there in the bag?
(a)
Total extra number of beads that Eva will need = 18
Number of extra beads that Eva will give to each pupil
= 7 - 4
= 3
Number of pupils that Eva has
= 18 ÷ 3
= 6
(b)
Number of beads that Eva has
= 4 x 6
= 24
Answer(s): (a) 6; (b) 24
