23 of his pens to Neave and bought 4 new pens. After that, he gave
49 of his remaining pens to his cousin and bought another 7 new pens. In the end, Justin had 37 pens.
- How many pens did Justin give to his cousin?
- How many pens did Justin have at first?
(a)
Fraction of his remaining pens after he gave to his cousin
= 1 -
49=
59 59 of his remaining pens = 37 - 7 = 30
19 of his remaining pens = 30 ÷ 5 = 6
49 of his remaining pens = 4 x 6 = 24
Number of pens that Justin gave to his cousin = 24
(b)
99 of his remaining pens = 9 x 6 = 54
Fraction of his total pens after he gave to Neave
= 1 -
23=
13 13 of his total pens = 54 - 4 = 50
33 of his total pens = 3 x 50 = 150
Number of pens that Justin had at first = 150
Answer(s): (a) 24; (b) 150
