- How many stamps did Billy receive in all?
- What percentage of the stamps that Billy received were foreign stamps?
(a)
Number of foreign stamps given
= 55% x 240
=
55100 x 240
= 132
Number of local stamps given to Billy
= 15% x 120
=
15100 x 120
= 18
Number of stamps received by Billy
= 132 + 18
= 150
(b)
Percentage of stamps received that were foreign stamps
=
132150 x 100%
= 88%
Answer(s): (a) 150; (b) 88%
