Tim had some beads. He gave
34 of his beads to Perry and bought 4 new beads. After that, he gave
35 of his remaining beads to his cousin and bought another 7 new beads. In the end, Tim had 21 beads.
- How many beads did Tim give to his cousin?
- How many beads did Tim have at first?
(a)
Fraction of his remaining beads after he gave to his cousin
= 1 -
35=
25 25 of his remaining beads = 21 - 7 = 14
15 of his remaining beads = 14 ÷ 2 = 7
35 of his remaining beads = 3 x 7 = 21
Number of beads that Tim gave to his cousin = 21
(b)
55 of his remaining beads = 5 x 7 = 35
Fraction of his total beads after he gave to Perry
= 1 -
34=
14 14 of his total beads = 35 - 4 = 31
44 of his total beads = 4 x 31 = 124
Number of beads that Tim had at first = 124
Answer(s): (a) 21; (b) 124
