Vaidev had some beads. He gave
23 of his beads to Carl and bought 4 new beads. After that, he gave
35 of his remaining beads to his sister and bought another 7 new beads. In the end, Vaidev had 33 beads.
- How many beads did Vaidev give to his sister?
- How many beads did Vaidev have at first?
(a)
Fraction of his remaining beads after he gave to his sister
= 1 -
35=
25 25 of his remaining beads = 33 - 7 = 26
15 of his remaining beads = 26 ÷ 2 = 13
35 of his remaining beads = 3 x 13 = 39
Number of beads that Vaidev gave to his sister = 39
(b)
55 of his remaining beads = 5 x 13 = 65
Fraction of his total beads after he gave to Carl
= 1 -
23=
13 13 of his total beads = 65 - 4 = 61
33 of his total beads = 3 x 61 = 183
Number of beads that Vaidev had at first = 183
Answer(s): (a) 39; (b) 183
