23 of his stamps to John and bought 4 new stamps. After that, he gave
27 of his remaining stamps to his cousin and bought another 7 new stamps. In the end, Xavier had 22 stamps.
- How many stamps did Xavier give to his cousin?
- How many stamps did Xavier have at first?
(a)
Fraction of his remaining stamps after he gave to his cousin
= 1 -
27=
57 57 of his remaining stamps = 22 - 7 = 15
17 of his remaining stamps = 15 ÷ 5 = 3
27 of his remaining stamps = 2 x 3 = 6
Number of stamps that Xavier gave to his cousin = 6
(b)
77 of his remaining stamps = 7 x 3 = 21
Fraction of his total stamps after he gave to John
= 1 -
23=
13 13 of his total stamps = 21 - 4 = 17
33 of his total stamps = 3 x 17 = 51
Number of stamps that Xavier had at first = 51
Answer(s): (a) 6; (b) 51
