Nicole has some marbles in a bag. The number of marbles is less than 40. If she gives 6 marbles to each pupil, she will have none left. If she gives 9 marbles to each pupil, she will need 15 more marbles.
- How many pupils does Nicole have?
- How many marbles are there in the bag?
(a)
Total extra number of marbles that Nicole will need = 15
Number of extra marbles that Nicole will give to each pupil
= 9 - 6
= 3
Number of pupils that Nicole has
= 15 ÷ 3
= 5
(b)
Number of marbles that Nicole has
= 6 x 5
= 30
Answer(s): (a) 5; (b) 30
