Shiyun sold orchids and carnations in her shop on Mother's Day. 70% of the flowers she sold on that day were orchids and she sold 72 carnations.
- What was the total number of flowers sold?
- 60% of the flowers in the shop were sold on that day. 75% of the flowers left were carnations. How many carnations were left?
70% =
70100 =
710 Total number of flowers = 10 u
Number of orchids = 7 u
Number of carnations
= 10 u - 7 u
= 3 u
3 u = 72
1 u = 72 ÷ 3 = 24
Total number of flowers sold
= 10 u
= 10 x 24
= 240
Percent of flowers left
= 100% - 60%
= 40%
60% of flowers = 240
1% of flowers = 240 ÷ 60 = 4
40% of flowers = 40 x 4 = 160
Number of flowers left = 160
Number of carnations left
= 75% x 160
=
75100 x 160
= 120
Answer(s): (a) 240; (b) 120
