Ian had some beads. He gave
67 of his beads to Tom and bought 4 new beads. After that, he gave
38 of his remaining beads to his brother and bought another 7 new beads. In the end, Ian had 27 beads.
- How many beads did Ian give to his brother?
- How many beads did Ian have at first?
(a)
Fraction of his remaining beads after he gave to his brother
= 1 -
38=
58 58 of his remaining beads = 27 - 7 = 20
18 of his remaining beads = 20 ÷ 5 = 4
38 of his remaining beads = 3 x 4 = 12
Number of beads that Ian gave to his brother = 12
(b)
88 of his remaining beads = 8 x 4 = 32
Fraction of his total beads after he gave to Tom
= 1 -
67=
17 17 of his total beads = 32 - 4 = 28
77 of his total beads = 7 x 28 = 196
Number of beads that Ian had at first = 196
Answer(s): (a) 12; (b) 196
