Peter had some beads. He gave
56 of his beads to Billy and bought 4 new beads. After that, he gave
49 of his remaining beads to his cousin and bought another 7 new beads. In the end, Peter had 27 beads.
- How many beads did Peter give to his cousin?
- How many beads did Peter have at first?
(a)
Fraction of his remaining beads after he gave to his cousin
= 1 -
49=
59 59 of his remaining beads = 27 - 7 = 20
19 of his remaining beads = 20 ÷ 5 = 4
49 of his remaining beads = 4 x 4 = 16
Number of beads that Peter gave to his cousin = 16
(b)
99 of his remaining beads = 9 x 4 = 36
Fraction of his total beads after he gave to Billy
= 1 -
56=
16 16 of his total beads = 36 - 4 = 32
66 of his total beads = 6 x 32 = 192
Number of beads that Peter had at first = 192
Answer(s): (a) 16; (b) 192
