Tim had some stamps. He gave
67 of his stamps to Lee and bought 4 new stamps. After that, he gave
49 of his remaining stamps to his cousin and bought another 7 new stamps. In the end, Tim had 22 stamps.
- How many stamps did Tim give to his cousin?
- How many stamps did Tim have at first?
(a)
Fraction of his remaining stamps after he gave to his cousin
= 1 -
49=
59 59 of his remaining stamps = 22 - 7 = 15
19 of his remaining stamps = 15 ÷ 5 = 3
49 of his remaining stamps = 4 x 3 = 12
Number of stamps that Tim gave to his cousin = 12
(b)
99 of his remaining stamps = 9 x 3 = 27
Fraction of his total stamps after he gave to Lee
= 1 -
67=
17 17 of his total stamps = 27 - 4 = 23
77 of his total stamps = 7 x 23 = 161
Number of stamps that Tim had at first = 161
Answer(s): (a) 12; (b) 161
