- How many stamps did Ivan receive in all?
- What percentage of the stamps that Ivan received were foreign stamps?
(a)
Number of foreign stamps given
= 45% x 180
=
45100 x 180
= 81
Number of local stamps given to Ivan
= 10% x 90
=
10100 x 90
= 9
Number of stamps received by Ivan
= 81 + 9
= 90
(b)
Percentage of stamps received that were foreign stamps
=
8190 x 100%
= 90%
Answer(s): (a) 90; (b) 90%
